Poor Fuel Fill Quality

Problem

Causes

DEFINITION: During the fuelling process a continual, occasional, or no-fuel nozzle shut-off condition has occurred.

Difficult to fill

    • Fuel fill limiter vent valve stuck closed
    • Evaporative emission (EVAP) canister restricted
    • EVAP vent valve stuck closed
    • Hose between canister and canister vent solenoid twisted or kinked if applicable
    • High fuel temperature
    • Fuel filler hose is kinked
    • Faulty dispensing nozzle
    • Ignition switch ON, vent valve closed

Over fill

    • Fill limiter vent valve stuck open or leaking
    • Fuel inlet check valve stuck open

Pre-mature shut-off of the fuel dispensing nozzle occurs immediately after engaging dispensing nozzle, tank empty

    • Restricted vapour lines or fuel fill pipe
    • High fuel temperature
    • Inlet check valve at tank stuck closed, fill pipe full of fuel
    • Fuel tank full, gauge not accurate

Pre-mature shut-off of the fuel dispensing nozzle, more than 1/8 of tank capacity dispensed

    • Kinked, pinched or plugged lines in fuel tank vent system
    • EVAP vent valve stuck closed or restricted
    • EVAP canister restricted
    • Fuel limiting vent valve stuck closed or obstruction at top of fuel tank

Fuel Spitback

    • Restricted EVAP canister
    • High fuel temperature
    • Ignition switch ON, EVAP vent valve closed
