Replacing Fuel Pump

Well the fuel gauge stopped working at about half a tank and I'm assuming it's the fuel sending unit which is attached the pump. It suddenly started working again the other day, but then I ran out of gas when it said half a tank again. Plus I've got a rough idle and fuel pump is growing higher on the list of possibilities.

SO... Can anyone give me a basic run down of the procedure for replacing the fuel pump/sending unit? Do I have to drain and drop the tank?

I'm not sure on a '90 but on a '96 XJ all you have to do is jack it up so your rear axle can hang at full droop and the fuelpump is on the front of the tank.No need to drop the tank.Change the fuelfilter too. Hope that helps.....

The link above gives step by step instructions and tools needed. Is not that difficult since the pump is situated on the front side. Best of luck

I have a 90 xj and i did not have to drop the tank, took off the brackets and let the tank swing down, and there it was. i lost alot of fuel because mine decided to go out with a full tank. but all in all it was a quit easy fix and it was my first time doing it.
