Change in-tank fuel pump 1990 Jeep Cherokee
All good stuff here. Thanks to all posts, my experience was great. I position the car for the lift, disconnected the battery, and siphoned all the gas from the gas tank that I could. Then I lifted the car with a two-post lift,
Next, I disconnected the electrical connection and fuel lines. The biggest problem there was that one of the clamp screws was difficult to get to.
Then went to work removing the lock ring. Since the procedure calls for using a brass drift, I used both a brass drift and a brass hammer to reduce the risk of spark. The ring came right out and so did the pump. The only hitch here was that the rubber stopper-looking part that the fuel intake goes into stayed in the tank. With no room to spare I got my arm in there up to my elbow and retrieved the stopper.
I coated the new O-ring with a film of oil. Putting the pump back in required careful placement and then I diddled around for a little while getting the pump in exactly the right place so that the O ring would seat properly. Once the O-ring was properly seated, I used the drift to seat the lock ring.
Then I just reconnected the hoses, plugged in the electrical connector and installed the two zip ties that were supplied with the pump to hold the hoses in place.
If I had not had a lift, I think it would have been more difficult to be able to get my arm positioned such that I could get it into the fuel tank to remove the rubber stopper looking part.
There was plenty of room to remove and install the pump with the tank left in place once the suspension was stretched out with the weight of the wheels and axle.
The whole job, including siphoning the tank was about 90 minutes.
