How do you lower the fuel tank on Isuzu trooper?

Answer 1

To lower the tank you could let the air out of the tires. To remove the tank you would need to remove the crash armor to get to the mounting bolts of the tank to chassis. Jeeps have straps and no armor. Then if you had fuel in there it could be drained by the PLUG at the bottom of the tank, all fuel drains out. With troopers a five gallon bucket will slide under nicely (providing you did not let air out of the tires) ;) First you must determine how much fuel is in the tank, too much and it will make the tank very unbalanced when trying to remove in other words the less fuel the better (you may need to drain fuel). You take a floor jack and place a piece of wood between the floor jack and the tank so that you don't puncture the tank, you then remove the screws on the lip of the tank, loosen and remove the filler neck from the tank, then disconnect the electrical connections and hoses that go to the tank. On the top of the tank where the hoses were connected you will see about 8 screws remove the screws and pull out the fuel pump, you then must remove the fuel pump from the sending unit assembly do not remove until you have the new pump if you have a camera take a picture so you can put it back as you found it. I have done this on a 1990 trooper on 3 occasions, what I have told you is for that year trooper but there should not be much difference from any other trooper. Good luck
