Fill Procedure

If a tank has less than 690 +/- 340 kPa (7.0 +/- 3.5 kgf/cm² 100 +/- 50 psi) of internal pressure and is at an ambient temperature of 32°F (0°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/cm² , 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.
