Fuel pump replacement procedures.
Dear fellows,

Is it possible to replace the fuel pump of the WJ without completely removing the petrol tank, i.e., lowering half without removing all the screws that retains the tank in it place?

Best regards,

No, that will not be possible. You will need to lower the complete tank to get access to the access cover. The tank is held in place by two large straps. You can change the whole pump assy with float, or only the refill.

Yes it is possible if you cut a hole in the correct spot. I know because my buddy replaced his fuel pump, was dead set on not removing the tank, and succeeded. It's definitely not a "proper fix" and most people would say not to do it. I even told him I wouldn't cut an opening w/ an angle grinder right next to the gas tank and I still wouldn't recommend it. But he did it and got the pump changed w/out dropping the tank or setting the Jeep on fire. I'll ask him when I see him on Monday if he can send me some pictures where he cut the hole.

Well, why wait for pictures right? I did a quick Google search and it yielded this thread where someone else cut through the spare tire well and changed their pump. It includes a couple pictures where someone made the cut. Again, this isn't something I would recommend or do to my Jeep......but it's possible.

*EDIT* Just talked to him and he'll have to get pictures tomorrow when it's light. He said he would start by carefully drilling a large hole and then using tin snips from there to get it cut out.

Re: Fuel pump replacement procedures.
Thank you for the replies. The question was because someone told it wold be possible to replace the fuel pump lowering only the front part of the petrol tank, hinging it in a 45 degree, without completely removing it, gaining access to the pump. If someone aptentend to do it, which could be the possible consequences?
Best regards,

Re: Fuel pump replacement procedures.
The tank hangs on two bands, so theoreticly removing the rear bolts from both bands could make the rear swing down. This would bend the metal from the bands and you still have a marginal space. I even Wonder if it would be possible to get the pump unit out, which has the same height as the tank itself. If you come to this point that you lower one side, why not lowering it completely? I had put a garage jack below the tank with a large piece of wood and lowered it after removing both bands. Then you can roll it aft from under the jeep. Putting the rear on stands will give you more space, eventhough i didn't do it. The tank must be empty as far as possible.

Thank you all for the answers.... They clarified my understanding that the mechanic told nonsense, so the job wil be fixed.
Best regards.
