Normal Operation
WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
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, if equipped (part of the fuel pump [FP] module)
