Installing a fuel pump in a 1995 Jeep Wrangler requires removal of the fuel tank. The fuel pump and sending unit are located together within the fuel tank; the nice thing about the 1995 Jeep is that the fuel pump can be installed individually. Many other domestic vehicles today have expensive modules that contain the sending unit and fuel pump but have no provisions to separate the two. From the Jeep you can remove the pump from the sending unit, so the entire module does not have to be replaced.
Raise the back of the Jeep and support it on jack stands. Place the jack stands under the frame so they do not interfere with the removal of the fuel tank. Relieve the fuel pressure by pushing the Schraeder valve on the fuel rail. Place a rag over the valve to capture the small amount of fuel dispelled. If the particular model does not have a Schraeder, simply loosen the fuel line at the fuel rail slightly and it will drop the fuel pressure. Use a wrench to loosen the fuel line.
Disconnect the electrical fuel pump harness connector behind the fuel tank. Loosen the filler hose at the uppermost clamp. Remove the steel shield under the fuel tank, using the appropriate socket to remove the bolts. Place the floor jack under the fuel tank.
Remove the two bolts securing the fuel tank support straps, using a 15-mm deep well socket. Remove the two support straps. Lower the tank about six inches. The filler hose sticks, so twist and bend the hose with your hand to break it loose.
Disconnect all the fuel lines by squeezing the plastic tabs and pulling them off. Lower the tank the rest of the way, keeping in mind that the tank has fuel that could spill if the tank is tipped too much is any one direction. Lay the tank on the floor.
Remove the lock ring securing the pump to the tank. There are multiple styles possible for locking in the fuel pump. One is a lock ring, which is a circular ring with four or more tabs sticking up. This type locks the horizontal tabs on the lock ring under the tabs on the tank. Use a screwdriver and hammer to remove this ring by placing the screwdriver tip on one of the vertical tabs and tapping the screwdriver to push the ring counterclockwise. It will release. Install it by pushing it down to aligning it with the tabs. Tap it in the opposite direction. The next type has an obvious snap ring; pop the snap ring out, using the screwdriver. Yet another type has a screw on cap; simply twist the cap off.
Lift the fuel pump from the tank, taking care not to bend or destroy the sending unit in any way. Watch how the pump comes out of the tank, so you have a proper perspective as to the orientation for assembly. Pry the fuel strainer sock off with the screwdriver.
Disconnect the two electrical connectors on the top of the pump proper. Watch again for orientation. What comes apart has to go together the same way in order to work.
Lift the bottom of the pump slightly and angle it out of the support assembly. Loosen the plastic hose clamp on the upper part of the pump. Before you pull the fuel pump out of the support, look closely at the bottom of the pump. You will see that it is made with a concentric rise to it. Now look at the rubber bushing still in the cradle under it and you can see it has the same shape, which also is incorporated in the cradle itself. The pump must be installed with this orientation or the fuel filter sock will not fit, plus the bottom pickup on the pump will be blocked and will not pick up fuel. Pull the pump out of the hose and discard the pump.
Install the pump and complete the job in reverse order of removal
