Under normal operation, fuel should flow at a steady rate through the fuel tank filler pipe into the fuel tank. As fuel enters the fuel tank air is vented through the filler pipe or the on-board refueling vapor recovery (ORVR) system.

Possible Causes
- Fuel tank filler pipe vent tube, if equipped
- Fuel tank filler pipe
- Evaporative emission (EVAP) system
- Fuel tank inlet check valve (part of the fuel tank)
- Fuel level vent valve, (mounted on the fuel tank)
