9. If all cylinders are to be tested and defueled: start with cylinder #1 and work through the system in order
until all cylinders have been tested. If only some of the cylinders are to be defueled and tested: leave
the valve manual knobs closed on the cylinders which are not to be defueled.
Cylinders on which valve manual knobs are not opened will NOT be defueled and will remain pressurized.

10. When performing this test confirm the following:
a. Electrical solenoid cylinder valves are energized.
b. BDN defuel nozzle is connected so the system can defuel. Refer to Section 5.4.2.
c. Bleed valve (9) on the Manifilter is open to prevent pressure build up in the fuel supply plumbing.
Figure A2
d. HP gauge (5) on the FMM reads zero. Figure A3
11. Starting with cylinder #1 (or the first cylinder to be tested), slowly open the manual knob on the valve.
Listen for the sounds of gas flowing out of the cylinder, as soon as the flow of gas is detected, close the
valve. Gas flow indicates the solenoid cylinder valve has opened properly and is functioning properly.
If no gas flow is detected, continue to open the manual valve knob until fully opened. If gas flow is not
heard, the solenoid cylinder valve is not functioning properly.

a. Close the manual valve, record that this solenoid is not functioning, and the solenoid cylinder valve
will require disassembly to depressurize the cylinder.
b. Repeat this test of slowly opening the manual valve knob, listening for gas flow, and closing the
manual valve knob on all cylinders requiring defueling.
c. Carefully note any cylinders where the solenoid cylinder valve is failed closed and not allowing the
cylinder to defuel.
All cylinders on which the solenoid cylinder valve fails to open properly will require disassembly
to depressurize the cylinder. Refer to Section A2.

12. Once all electric solenoid cylinder valves have been tested, close bleed valve (9). Figure A2
13. Close manual cylinder valves on all cylinders with failed solenoid valves. Figures A4 and A5
14. Open manual cylinder valves on all cylinders to be defueled with functioning solenoid valves. Figure A4
and A5
15. Verify BDN defuel nozzle is properly connected. Refer to Section 5.4.2.
16. Defuel all cylinders with functioning solenoid valves. Slowly open FMM defuel valve (7) and adjust for a
slow and steady flow to avoid freeze up. Figure A2
On all cylinders where no gas flow was heard (which means the solenoid valve is failed), the solenoid valve
must be disassembled and manually vented to depressurize the cylinder. Refer to Section 4. Solenoid valve
disassembly, and Section 5. for solenoid valve function test and cylinder venting after valve disassembly.

17. Once the defueling procedure on the cylinders with functioning solenoid valves is complete, AND
cylinders with non-functioning solenoid valves have been dissembled and vented manually, verify FMM
HP gauge (5) reads zero psi/bar. Figure A3

This method requires electrical power to actuate the electric solenoid cylinder valves.
1. Complete all steps in Section 5.
2. Confirm all manual valve knobs on all cylinders to be defueled are open to allow these cylinders to defuel.
Figure A1
Manual valve knobs should remain closed on all cylinders which are not to be defueled.

3. Verify FMM 1/4-turn manual shutoff valve (1) is in the ON/OPEN position. Figure A3
4. Defuel the CNG supply plumbing and cylinders as follows:
a. When defueling, all electric solenoid cylinder valves should be energized (open).
b. Verify OEM vehicle battery disconnect switch is ON. Figure 2
c. To energize the cylinder solenoid valves for defueling, use the defuel switch inside the rear run box
(located behind an access panel in the engine compartment). Refer to OEM vehicle manual.
5. Slowly open FMM defuel valve (7) and adjust for a slow and steady flow to avoid freeze up. Figure A2
6. Continue defueling until FMM HP gauge (3) reads zero psi/bar. Figure A3
7. Open bleed valve (9) on the Manifilter and leave it open during this procedure. Figure A2
8. If all cylinders are to be tested and defueled: start with cylinder #1 and work through the system in order
until all cylinders have been tested. If only some of the cylinders are to be defueled and tested: leave the
valve manual knobs closed on the cylinders which are not to be defueled.
Cylinders on which valve manual knobs are not opened will NOT be defueled and will remain pressurized.

9. Turn off the defuel switch inside the rear run box (located behind an access panel in the engine
compartment) to turn off power to the electric cylinder solenoid valves. Refer to OEM vehicle manual.

11. Disassemble and test each solenoid valve. If the valve is functioning correctly, there will be no gas
pressure in the cylinder and no gas will flow out of the disassembled valve. Carefully test each valve.
Any valves which exhaust gas in Step 11 have failed in the closed position and must be replaced before
returning unit to service.

12. On all valves which exhaust gas in Step 9, leave the manual valve knob open to fully exhaust all the
pressure in the cylinder. Leave the manual valve knob in the fully open position. Figure A5
13. Reassemble the valves which function properly after testing and replace any that are failed closed.
Reassemble solenoid valve. Refer to Section A6.
14. Once all the valves on the cylinders to be defueled have been tested, AND all cylinders with a failed
closed valve have been manually vented, the cylinders have been depressurized and work can be
performed on the cylinder valves, PRDs or associated plumbing.
Before returning unit to service, a leak test and solenoid function test must be performed.

15. Perform a leak test with Swagelok® Snoop® leak detection fluid. Repair any leaks. Refer to Section 4.2.
16. Test for proper solenoid valve function:
a. Start engine and allow engine to idle for at least two minutes.
b. Operate cylinder solenoid valve test switch (located behind an access panel in the engine
compartment). This will de-energize the electric solenoid cylinder valve causing the valves to close.
c. Pressure on the HP gauge (5) should drop and the engine should stall due to lack of fuel within ten
minutes. Figure A3
d. If the engine does not stall, one or more solenoid cylinder valves are not functioning correctly. The
valve system will require additional testing to determine which valves are not functioning correctly
and require replacement.
17. Once the leak test and solenoid tests are completed successfully, the unit can be returned to service.

A3. Defueling When No Battery Power is Available
If electrical power is not available to actuate the electric solenoid cylinder valves, the recommended procedure
is to restore battery power on the vehicle so the solenoid valves can function.
This procedure requires disassembly of the solenoid cylinder valves.

Fully close the manual cylinder valve knobs on all cylinders. Verify all manual valves are fully closed by turning
knobs fully clockwise. Figure A1
1. Verify FMM 1/4-turn manual shutoff valve is in the ON/OPEN position. Figure A3
2. Using the defueling nozzle, slowly open the defuel valve to depressurize the CNG tubing and the fuel
manifold. Refer to Section 5.4.2.
3. When the FMM HP gauge (3) reads zero, open the bleed valve (9) on the Manifilter. Figures A2 and A3
4. Verify the following:
a. FMM 1/4-turn manual shutoff valve (1) is in the ON/OPEN position. Figure A3
b. FMM HP gauge (5) reads zero. Figure A3
c. Bleed valve (9) is open and no gas is being vented from the bleed valve. Figure A2

6. After solenoid valve disassembly, reassemble solenoid valve without the plunger and spring (refer Step
7), and defuel the cylinders using the defuel nozzle as described in Section 5.
7. To reassemble the solenoid valve without the plunger and defuel using the defuel nozzle, perform the
following:
a. Reassemble valve stem to valve body but do not install plunger and spring. Figures A8, A9 and A10
Torque valve stem to 25 ft-lbs (35 Nm).
b. Omitting plunger and spring overrides solenoid function and allows gas to flow through the solenoid
valve without electrical power.
8. Before proceeding:
a. Verify all cylinders to be defueled have had the spring and plunger removed
b. Verify all valve stems have been reinstalled and properly torqued to 25 ft-lbs (35 Nm).
c. Verify the pressure on the HP gauge (3) continues to read zero. Figure A3
9. Close bleed valve (9) and defuel valve (7). Figure A2
10. Verify defuel nozzle is properly connected. Refer to Section 5.4.2.
11. Verify FMM 1/4-turn manual shutoff valve (1) is in the ON/OPEN position. Figure A3
12. Slowly open the manual cylinder valves on all cylinders to be defueled. Listen and smell for any signs of
gas leakage. No leakage should occur.
If any leakage is detected, close manual cylinder valve knobs and repair leaks.

13. When all the manual cylinder valves are open, verify the cylinder pressure reading on the HP gauge (3).
Figure A3
14. Using the defuel valve (7) to adjust the defuel flow rate, proceed to defuel the system. Figure A2
15. Once the HP gauge (3) reads zero, slowly open the bleed valve (9) to vent any residual pressure. Figures
A2 and A3
16. When the HP gauge (3) reads zero and no gas is venting from the bleed valve (9), system defueling is
complete. Figures A2 and A3
Only cylinders with the manual valve open and the solenoid plunger removed will be depressurized. Any
cylinders with the manual cylinder valve closed or the plunger installed in the solenoid will remain
pressurized.

17. After completing all repairs before repressurizing the system, the plunger and spring must be reinstalled.
Refer to Section A6.
18. When work is completed, the valve may be reassembled or replaced as needed.
19. Before returning unit back to service, complete a leak test (Section 4.2.) and a solenoid valve function
test (Section A9).
20. Perform a leak test and repair any leaks. Perform the leak test in three stages:
a. Slowly pressurize the cylinders to approximately 100 psi (6.89 bar) and check for leaks at all solenoid
valves and any fuel line connections that were disconnected. Refer to Section 4.2.
b. Next, slowly pressurize cylinders to approximately 1000 psi (68.9 bar) and check for leaks especially
around the solenoid valves and line connections that were disassembled. Refer to Section 4.2.

c. Finally, fill the system to full service pressure and complete the final leak test. Refer to Section 4.2.
21. Using the cylinder solenoid test switch (located in the rear run box behind a panel in the engine
compartment) check for proper cylinder solenoid valve function:
a. Start engine and allow the engine to idle for at least two minutes
b. Operate the cylinder solenoid test switch (located in the rear run box behind a panel in the engine
compartment). This will de-energize the electric solenoid cylinder valve causing the valves to close.
Refer to vehicle OEM manual.
c. The pressure on the FMM HP gauge (3) should drop, and the engine should stall due to lack of fuel
within ten minutes. Figure A3
If the engine does not stall, one or more solenoid cylinder valves are not functioning correctly. The valve system
will require additional testing to determine which valves are not functioning correctly and require replacement.

22. Once the leak test and solenoid test are completed successfully, the unit can be returned to service.

A5. Solenoid Valve Function Test and Cylinder Venting After Valve Disassembly
With the solenoid cylinder valve disassembled, the only thing preventing gas flow is the manual valve.
Secure area around the cylinders and verify that no loose equipment is in the area. Remove all tools, rags, etc.
Any objects not securely attached to the roof may cause serious injury when defueling begins.

Open valve ports are live and high-pressure gas up to 4500 psi (310 bar) may flow out of the disassembled valve
when the manual cylinder valve is opened. Do not place hands or any part of body above or near the open valve
ports.

Use the following procedure to:

Confirm the cylinder is depressurized,
OR

To depressurize the cylinder if the solenoid has failed closed.

1. Slowly turn manual knob on cylinder valve counterclockwise to open. If the cylinder is pressurized, gas
will vent out the open valve ports. Figures A4 and A5
If gas DOES come out when the valve is opened the cylinder is NOT depressurized, and the solenoid valve
has failed closed. Solenoid cylinder valve replacement is required once the cylinder is fully depressurized.
Control the rate of defueling using the cylinder manual valve knob. As the cylinder pressure drops, the valve
can be opened further to increase the rate of defueling. Figures A4 and A5

2. Allow gas to flow until gas stops flowing. When the stops flowing, slowly open manual valve knob until
fully open. Once the gas stops flowing with the valve fully open the cylinder is fully depressurized. Figures

GilligeBay logo CNG Five Cylinder System Operation Manual

A8. Re-orient Cylinder
1. Disconnect PRD vent plumbing.
Always use two wrenches when removing fitting nuts from fittings.
Do not loosen the PRD fitting in the end of the cylinder.
2. Once all fuel tubes have been removed from both ends of the cylinder, loosen the 1/2-in. neck block
bolts on the valve end of the cylinder using a 3/4-in. wrench.
It is not necessary to touch the neck block bolts on the PRD end of the cylinder.

3. Gently rotate cylinder by hand to achieve the desired valve position.
4. Test-fit all fuel tubes to ensure proper alignment.
Tighten 1/2-in. neck block bolts to 85 ft-lbs (115.2 Nm) minimum to 90 ft-lbs (122.0 Nm)
maximum.
5. Loosen and re-orient the (#8 JIC) elbow fitting on the PRD end of the cylinder.
6. Re-install all fuel tubes and PRD tubes.
7. Pressure test per Section 4.2.

A9. Solenoid Cylinder Valve Function Tests
Reduced vehicle range is usually the first indication of a solenoid cylinder valve has failed in the closed position.
If a failed closed cylinder solenoid valve is suspected, perform the following troubleshooting steps to isolate the
problem.
System pressure should be at least 1200 psi (82.7 bar) when conducting these tests.

A9.1. Test for a Failed Closed Solenoid
1. Confirm manual valve knobs on all cylinders are open. Figure A4
2. Disconnect the electrical connector to all solenoid cylinder valves. Figure A4
OR
Turn off solenoid cylinder test switch on the rear run box (located behind an access panel in the engine
compartment).
3. Start the engine and run the engine until it stalls. If the vehicle continues to run without significant
pressure drop (as observed on the FMM HP gauge), then one or more cylinders have solenoid valves
may have failed open. Skip to Section A9.2.
4. Verify fuel system tubing is empty by confirming a zero psi/bar reading on FMM HP gauge (3). Figure 3
5. Open FMM bleed valve (9) on the Manifilter and leave open. Figure 4
6. Apply 24V to a single solenoid cylinder valve.
If the solenoid cylinder valve opens and fuel can be heard rushing through the fuel tubes, disconnect the
24V power supply: solenoid cylinder valve is operational.

7. If no fuel is heard coming out of the cylinder, confirm there is 24V at the solenoid coil.
ENP-756 REV E 8/3/2022

Gillig CNG Five Cylinder System Operation Manual

8. If 24V is present: remove and replace the solenoid coil with a different coil (refer to Section A4.) and
repeat Section A9.1.
9. If no fuel is heard coming out of the cylinder, it is likely that solenoid cylinder valve internal parts have
failed.
Failed solenoid cylinder valve must be disassembled per the procedure in Section A4.

10. If fuel is heard coming out of the cylinder after the second coil is installed and tested, then the first coil
has failed and must be replaced.
If a solenoid cylinder valve has failed in the closed position the vehicle must be removed from service
and the valve replaced.

11. After the electric solenoid cylinder valve on cylinder #1 has been evaluated, repeat Steps 1 through 10
for each cylinder.

A9.2. Test for a Failed Open Solenoid
1. Close manual valve knobs on all cylinders. Figure A1
2. Start vehicle and run engine until it stalls.
3. De-energize all solenoid cylinder valves.
Ignition key must be in the OFF position.

4. Slowly open the manual knob on each solenoid cylinder valve. Figure A1. If fuel can be heard rushing
through the cylinder into the fuel lines, the solenoid cylinder valve has failed in the open position and
must be replaced.
If a solenoid cylinder valve has failed in the open position the vehicle must be removed from service and
the valve replaced.
