How do you Remove fuel tank jeep wrangler Yj 1990?

Answer 1

If you have a little time to play with it's not a terrible task short of rust..

Unless the wrangler is "raised" chock the front wheels and raise the rear of the Jeep. As a precaution of course always unhook the negative battery terminal first to prevent any possibility of a spark from occurring when you have fuel vapors floating about.

Remove the small cover at lower rear of the driver side fender well. It uses a set of push lock fasteners. Pull the pins out a little then pull the fasteners out, and remove the small panel. From here you have access to the tank fill and vent hoses. Remove the hose clamps and hoses from the tank.

Disconnect the fuel lines (driver side at top front of tank) if this is a 15 Gallon tank.

If it is a 20 gallon tank, you do not need to disconnect the lines yet.

place a jack under the tank/Skid plate assembly. Transmission jacks work well, though I use a standard hydraulic floor jack.

From under the jeep remove the nuts from the FRONT of the skid plate, There should be three. This is where the rust issue could make it a P.I.T.A., remember penetrating oil is your friend! Too rusty I find a decent pair of vise grips on the bolt and a socket and breaker bar on the nut and snap them off works.

now to the rear of the jeep and remove the skid plate nuts (4 of them). These are 5/16 bolts, (1/2" socket). DO NOT remove the 2 tank strap nuts (3/8 bolts, 9/16" Socket).

Slowly lower the tank a little bit. If this is a 15 Gallon tank, you already removed the lines now when you can get a hand over the tank from under the jeep, feel around for and disconnect the fuel send connector.

If this is a 20 gallon tank, continue slowly lowering, you may have to lower the passenger side most all the way and shift the tank towards the passenger side to clear it. Notice as you lower it, the lines and sender wires on top of tank. The group is normally retained there with tape, remove the tape to allow slack, and when you can reach them from rear of jeep, disconnect the sender connector and fuel/return/vent lines. On either size tank continue slowly lowering and pull tank out from rear of jeep.

Tank is strapped to the skid plate, which is why you remove the whole unit. Now remove the straps if you are replacing the tank. Just replacing sender/pick-up etc, you can leave it strapped in place.

Re-installation is the exact reverse of removal.
