The problem I am having is related to the fuel delivery system I THINK . The truck stutters and stalls after driving for awhile it cuts off and refuses to restart until it has sat for a half hour or so then it will start and run for the next hour or so. mind you I drive an average of 250 miles a day making deliveries.

I had it's codes checked and everything pointed to the cam shaft sensor (whch I replaced) and replaced all plugs, points and rotor button plus wires.

The codes only showed a malfuction and not a fault failure.

This is why I think it is related to the fuel pump and or fuel pump screens.

The parts store told me that there are two screens to be replaced within the tank one on the module and the other in the tank is this true? and how easy are they to replace by myself ?

Welcome, I'd use a gage and check fuel pressure, first. Some of the national brand autostores might loan you a fuel pressure gage? You can call and ask.

I believe there is a filter/regulator, that sits on top of the fuel pump assembly. Also, there should be a strainer on the intake end of pump. The partsbook showed a strainer.

My info says 44--54 psi.

The screen is in the tank. The filter/regulator is not in the tank. Sits on top of the fuel pump assembly.

OK changed the screen and it seemed to work but when driving along the jeep started to buck like before RPM's went to 3K before the thing shut down. I waited 15 minutes and the jeep runs once again but it wants to continue to buck and stall ......ANY ideas

I'd still check fuel pressure. The national brand autostores used to check codes for free. You can call and ask?

When you say that there is a filter on top of the pump do you mean inside of the module ? and how do you get the damn thjng apart to replace the pump anyway? it seemed like a sealed assembly

Hi, pressure regulator/filter combination. My parts book, showed this. As far as how to get it off, I guess I'd have to look at it. I can't remember every year-- make -- model I ever worked on. I'm getting old.lol
