Diagnostic Aids

If customers concern is related to fast filling fuel tank refer to the following:

• Fast-filling CNG fuel tank causes fuel to heat-up and expand.
• Fuel temperature may remain hotter than ambient Intake Air Temperature (IAT) for up to 3 hours after filling.
• Fuel tank pressure may decrease by up to 800 psi within 3 hours of fast filling. Fuel tank will not completely fill during a fast fill, due to expansion of fuel. Fuel gauge will display full as long as fuel is hot. Fuel gauge display reading will decrease as fuel cools.
