Vehicle is Difficult to Fill with Fuel or Filling Station Pump Shuts Off Before Tank is Full (Replace Tank Filler Hose)

Some customers may comment that their vehicle is difficult to fill with fuel or when filling, the pump continuously shuts off before the tank is full.

This condition may be caused by back pressure within the fuel filler hose. This back pressure trips the fuel nozzle prior to filling the tank, or results in a hard to fill condition.
