WARNING:
- Compressed natural gas is flammable and highly explosive. You could be killed or seriously injured if leaking natural gas is ignited.
- Stop the engine, and keep heat, sparks and flames away.


NOTE: When you relieve the gas from the fuel tank, the fuel tank cannot be reused. Do not reinstall the original fuel tank. Install a new fuel tank.

2. Install a new fuel tank, fuel tank bands and fuel tank frame on the tank fixture.




3. Tighten the bolts.




4. Tighten the nuts.




5. Tighten the nuts. The nuts should be tightened until a gap of 11.7 mm (15/32 in.) at the centerline of the bolt is obtained.

7. Mark the fuel tank and the fuel tank bands.
8. Apply PAG oil to a new O-ring, and carefully install it onto its proper position.

Fill Procedure
If a tank has less than 690 ± 340 kPa (7.0 ± 3.5 kgf/sq.cm, 100 ± 50 psi) of internal pressure and is at an ambient temperature of 32 degree F (0 degree C) or less, follow the procedure below. Otherwise, fill the tank normally.

1. Fill the fuel tank to 4,800 ± 340 kPa (49.2 ± 3.5 kgf/sq.cm, 700 ± 50 psi) slowly (from a compressor, not from a cascade storage system).
2. Wait one hour.
3. Fill the rest of the tank normally.
