11. Install the hoses at the bottom of the plate and tighten them making sure that their natural curve
will make them lay flat at the bottom of the tank.

12. Inside the tank, install the accessory plate inner frame (reuse the two tapered screws), apply Sika
221 grey sealant over the screw heads.

13. Install the accessory plate gasket # 032956 over the tank opening (clean both sides of the gasket
with rubbing alcohol first) and install the assembled accessory plate on the tank (reuse mounting

NOTE
-It is also possible to bond the gasket to the bottom of the accessory
plate using quick set superglue.

-Apply only a small drop of glue at the exterior edge of the screw holes
as shown.

14. Pressure-test the tank at 3 psi. Install caps at the fuel filler ends, cap the vent hose and fuel line
connections and connect a test valve with low pressure gauge at the tank outlet.

-

Accessory plate perimeter.

-

Fuel fittings.

NOTE
- The drain plug at the bottom of the tank is tested at the factory and does not need to be retested.
- If the pressure relief valve opens at 3 psi or below, the valve is defective and must be replaced.

Correct leaks as necessary, if no leaks are found, the tank is ready for re-installation.

fasteners when reinstalling the tank.
.
