RECALL

ISSUE ______________ ____________ __ __

CORRECTIVE ACTION________----___

Propane fuel lines may be crossed and/or
rubbing. Crossed and/or rubbing fuel lines may
become damaged from movement and develop
a leak.

Inspect fuel lines and if necessary reroute
propane fuel lines to ensure the lines are
secured parallel and are not rubbing.
Replace any damaged fuel line(s).

5. If the fuel lines are contacting the air intake tube, inspect for damage to the fuel lines and
follow reroute instructions.
NOTE: If any lines need replacing, obtain replacement parts before rerouting lines.

7. Fuel lines may have been installed where they contact each other. If the lines are rubbing
or crossed, then the fuel lines may become damaged. Remove the cable ties from both
heavy duty cable mounts and inspect the fuel lines for any damage. If the fuel line has
been damaged, follow fuel line replacement instructions.
NOTE: If any lines need replacing, obtain replacement parts before rerouting lines.

crossed and/or rubbing. These lines
must be rerouted, per instructions on

from both heavy duty cable mounts.
Note:
Do not remove heavy duty cable
mounts just the cable ties.

CAUTION: Allow engine and components to cool prior to performing these procedures to
prevent risk of severe burns.
WARNING: Technicians working with, or around, fuel systems should be properly trained to
utilize extreme care and caution at all times. Failure to exercise extreme caution and care may
lead to serious accidents which can result in property damage, personal injury and/or death.
WARNING: LPG is under pressure, wear adequate eye protection. When LPG is discharged into
the atmosphere the rapid change in pressure can cause a refrigerant condition in the fuel (quick
cooling) and can harm your skin or cause serious burns much like frostbite. Always wear gloves.
WARNING: Liquid propane is cold. The temperature of propane in its liquid state is -44o F
(-42o C). Wear eye and ear protection during venting and repair operations. Keep moisture away
from the valves. Failure to heed this warning can result in personal injury.
1. Park bus on level surface, apply parking brake, turn off ignition, remove key, and chock
wheels.
2. Disconnect batteries.
3. Open hood and locate propane fuel lines from FRPCM to the rear of the engine.
4. NOTE 1: Cable ties on both sides of the bracket were cut and removed during the
inspection process.
NOTE 2: If any line needs replacing, obtain replacement parts before rerouting lines.
NOTE 3: If the heavy duty cable mounts are missing during the inspection, please contact
Blue Bird Recall Administration at [email protected] for parts. Parts shown
below will be needed before lines can be rerouted because these support the dual clamp
ties.

RECALL

5. Using Photo’s 1, 2, 3, and 4 in the Proper Routing and Clamping Section as your
guide, reroute the four fuel lines to be parallel with each other. Install two or three
dual clamp ties Part Number 00024043 to maintain separation.
a. NOTE: It may be necessary to loosen the fuel lines on the bottom of the FRPCM
to reroute these fuel lines. Please follow Roush CLEANTECH
Depressurization Procedure at the end of the document for depressurization
procedure (purging) a system prior to loosening fuel lines. If lines need to be
disconnected from the FRPCM for rerouting, replace Jiffy Tite Fittings. Roush’s
description and part numbers for the 1/4 inch fitting is 25031 (2 per FRPCM, as
well as, 4 in the fuel lines) and for the 3/8 inch fitting part is 85672 (2 per
FRPCM). Please contact ROUSH CLEANTECH at Phone Number:
800.59.ROUSH or e-mail ROUSHcleantech.com with any questions regarding
Roush’s procedures.
b. Be sure to follow ALL of the Warnings and Cautions in the propane section of
Blue Bird Service Manual.
6. Maintain 1/2 inch minimum clearance between the throttle body/air intake tube and
the bottom of the fuel lines (See Photo 1).
7. If any fuel line has been damaged, replace fuel line(s) by following Roush
CLEANTECH Instructions at the end of this document. See Page 6 on how to
identify a good or damaged fuel line. Please contact ROUSH CLEANTECH at
Phone Number: 800.59.ROUSH or e-mail ROUSHcleantech.com with any
questions regarding Roush’s procedures.

8. After all fuel lines have been rerouted, repaired and/or replaced, check for leaks, check
all the surrounding components to be sure nothing has been displaced with this
rework. Place the bus back into service.

Visible fiberglass damage shown on
Roush Fuel Line. If the heat sleeve is
worn through to the point that the
fiberglass is visible like shown, then it is
recommended that it be replaced. As
long as the line underneath shows no
damage to the braid then a replacement
sleeve can be installed over the line.
