Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Diagnosing Fuel Fill Problems: 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 ORVR .
