How to Remove the Gas Tank From a 1994 Jeep Wrangler
- 1). Raise the rear of the Jeep Wrangler with a jack and support it on a set of jack stands positioned under the rear axle housing. Locate the two bolts in front of the gas tank that secure the tank straps to the cross member in front of the tank.
- 2). Position a floor jack under the center of the tank and place a wide piece of wood on the jack. Raise it until it is just touching the bottom of the tank. Loosen the two strap retaining bolts with a socket and ratchet. Work slowly, making sure to balance the weight of the tank on the floor jack.
- 3). Continue loosening the retaining bolts until they are free of the cross member. Pull the two support straps down and lower the jack slowly until you can reach the connections on the top of the tank.
- 4). Disconnect the electrical connector at the fuel pump/sender module. Lay the wiring harness aside and move to the fuel line connections. Loosen the clamps on the fuel lines. If these have never been removed, they will have spring clamps on them. Squeeze the tabs on the clamp together with a pair of pliers then slide them off the hose end.
- 5). Pull the hoses loose using a slight twisting motion. You may get a small amount of fuel from the end of the hose when you remove it. Set the hose aside and lower the jack and tank all the way down. Slide the tank out from under the Jeep.
