open up the gas cap on the rear fuel tank(in a quite area). with your ear to the fill hole get someone to turn the ignition to the on/run posision(without starting it and with the fuel tank selector on the rear tank). if you hear a buzzing your pump works. if not check to see if you have power to the pump. if you do your pump is no good. if no power then that's your problem. trace the wire to see if its broken.
18 gallon tank is in the rear...
I believe 18 gals. in front tank and 20 gals. in rear
Yes, you should have no problems.
no because if your tank leaks it is wrecked
The front tank is the main tank and the rear tank is the auxiliary tank.
Its in the fuel tank
Long wheelbase: front tank = 19.0 gal. rear tank = 18.2 gal. total = 37.2 gal. Short wheelbase: front tank = 16.5 gal. rear tank = 18.2 gal. total = 34.7 gal.
If your wondering why you get better fuel economy in the front tank is because it is an over flow tank. That mean when your running on the rear tank your are actually dumping fuel into the front tank when ever you hit your breaks hard and the engine also returns fuel to the front tank that isn't needed from the rear. that is why you get better millage on the front tank and worse on the rear tank.
SWITCH UP= FRONT TANK
The fuel tank is under the rear of the vehicle.
check wiring at fuel tank where fuel pump is located
You probably have a bad front tank fuel pump or you could have something wrong in the switch valve or selector switch, or even a problem in the wiring to the front fuel pump, but most likely a bad fuel pump.
