1991 f150 lariet 4x4 dual tanks - do i have an external fuel pump or not?
Both tank,s have internal pump,s.
First check the fuel filter,then the pump,s.
Both of them should not go out at same time,could be the fuel selector has gone bad,or the tank switch.
well that is better news then having to replace the fuel pumps, thanks for quick helpful advice.
