What is involved in taking the tank out and where can I find a drawing of the tank so that I may see the location of the pump on order to cut a whole in the floor to acess the pump without removing the tank.

I replaced the fuel pump in a 1995 Jeep Cherokee Sport without having to remove the gas tank. Maybe you can too in your '98 Grand Cher. If your fuel pump is accessed from the upper front of the gas tank-above the rear differential-then you should be able to remove the pump with the tank in place. It was easy on that jeep of my son's, took only about an hour or two.
Well there could be a problem withthe fuel pickup in the tank but personally I would just keep the tank full above a quarter. And that's speaking as a professional who could certainly take my own fuel tanks or pump/pickup assemblies out of my own cars if I had to. Removing fuel system components is a hazardous and even dangerous activity. If you were on a long cloverleaf and cornering a bit hard, it's not unusual to starve the engine for fuel with that little fuel in the tank.
When it stalls, turn the key back on and listen for the fuel pump. If you can't hear it it is going bad. Usually banging on the tank bottom will jolt it into coming back on. Pump wont set a code. Can't say for sure that's it but cps and pump are the two main causes of that kind of problem.
Likely you did a bad thing to the tank float when working on it If so, it will need to be taken down (again) and checked. First though check that the gauge is getting power at the attachment harness (pump and power side should have a voltage pulse and good tank grounding.)
What you brought is an tank and unit from 1995 JGC. from 1993 till 1995 they have the same fuel pump. 96'er Jeeps start with OBD - Systems and they have other fuel pumps. You can't change the plug ins, because you may have other fuel filter in your Granny. Check filter and fuel lines if they fit with the unit you brought. If not, you need another unit from a real 96'er Jeep
its not real hateful especially if the tank is low on fuel....you need to drop the tank out of the vehicle....the electrical connecto is on the drivers side in front of the tank mounted to the frame,,,,disconnect the fuel lines and undo the nuts holding the 2 straps...lower the tank and there is a plastic ring holding the pump in...loosen it counter clockwise and remove the pump
i had the same problem with my 96 jeep...apparently my ground wire for my pump had come disconnected, i used a little clamp to reattach it and havent had any problems out of it since...mite wanna try this before taking it into any shops
First install a fuel pressure tester on the fuel rail and check the
pressure during crank. It should be about 30 psi.If the pressure is not
good then it could be a bad fuel pump relay or fuel pump itself (in the
If the fuel pump pressure is good then you could have a bad crank sensor.
