Diagnosing Fuel Fill Problems: Notes

2000 Saturn SC2 Automatic, MP6SECTION Notes

Problems associated with refueling the vehicle such as premature shutoffs of the fill nozzle or inability to dispense fuel at a high rate are related to two areas:

  • A blocked inlet (i.e., the fill pipe).
  • The primary vent path is blocked or severely restricted.

Redesign of the fuel fill inlet and vent path was done as a result of Onboard Refueling and Vapor Recovery (ORVR) requirements. Refer to THEORY OF OPERATION - FUEL FILLING AND ORVRΒ .
