Has anyone changed a fuel pump?

Well guys I found a bad ass wrangler that I may be getting in a few weeks when the guy gets time to come up from D.C. Anyway it needs a new fuel pump, how hard is it to do and how long should it take? I have a friend who is a very skilled machanic.

The only PITA part of that job is you have to drop the fuel tank to get to the fuel tank. Once that is done, swapping the fuel pump is a minor thing. Make sure the problem is really the fuel pump, lots of other stuff can cause the engine computer to cut the power to the fuel pump. I had a bad ignition coil while offroading last month and the computer shut the fuel pump off once it noticed there was no spark getting to the cylinders.

The issue I ran into with changing my pump was if the tank was cold my tank would not seal my pump so I could twist the big lock nut onto it. If you run into this issue then let it sit out in the sun after you have cleaned the gasoline out good and then try to put the nut back on. You may run into the issue but some say they don't run into it. Took me days to figure that one out and I did it by mistake really. Another trick is to put a air hose in the intake of the tank and the pressure will inflate the tank so you can put the nut back on. Which ever

Not a big issue but budget in the cost of a new pump which is a few hundred depending on who you buy it with. Do your best to empty your tank and don't go by the gauge because it will be a pita going down. Have some tanks handy when you siphon the rest of the gas out also. Everything goes right it's not hard but that's a perfect world and I sure don't live in it.
