Guys the truck is back on the road again. I can't thank everyone enough for guiding me through this experience. As it turns out it was the element that was the culprit. Evidently there was a crack in the element housing where the harness plugs in which allowed air to be sucked into the...

Guys thanks for the part numbers they should help me a bunch. Illflem- I'm wondering about the cable harness. Is it the harness the creates a seal so that fuel doesn't leak and air doesn't enter? Or is it the element itself that is sealed? In other words if the harness is unpluged will the...

Illflem- How do I go about bypassing the heater? I'm all for that since I can't seem to locate the element or any related parts seperately. The local Cummins dealer seems to be having trouble locating anything related to a pre-heater. He's not even sure that the truck came with such a part on...

After pressurizing the system with low air pressure (through the fuel filler neck on the fuel tank) a leak was revealed. Initially air came out and then there was a good stream of fuel flowing from the plug recepticle on the pre-heater element. I wasn't sure if it was leaking from the gasket...

Illflem, unfortunately the fuel gauge doesn't work and I'm not sure how much fuel I lost when I drove home (about 20 miles) with the old lift pump leaking. I do know it was leaking at a pretty good rate because the underside of the truck was very wet and the were a couple of cars behind me that...

Malcolm, I don't believe I lost the pushrod. I say this because it required some inward pressure on the pump to get the two bolts started. I guess the only way to tell is to pull the pump back off? Assuming that the pushrod is intact does a new lift pump that is defective not allow one to...

Another day of working on the truck and it still won't run. I've looked at all the fuel lines and they seem to be ok. After doing a search I read that purging air out can be done by inserting an air supply into the filler neck of the fuel tank while the bleed valve is open essentially...

Well, I've tried pumping the plunger on the lift pump (so many times I've lost count) and I'm not able to get straight fuel at the bleed valve. I've tried with the fuel tank cap off per Malcolm's suggestion and I still get air bubbles at the bleed valve with very little fuel. Could the new lift...

Eric, I'll try the bleeder valve again maybe there is still some air in the system. I'll also give the injector line bleeding method a try. Malcolm, the pump is a Cummins part which I believe is made by Carter. I didn't try pumping the plunger with the fuel cap off, I'll give that a try...

Hi Eric. Thanks for the quick response. I should have mentioned that I did open what I think is the bleed valve. Is it the 10mm bolt atop the cannister housing toward the front of the housing? I hope that is it. There is also a doble banjo type fitting toward the rear or firewall side of the...

Hello to all on the TDR. As you've probably noticed this is my very first post so I'm hoping not to mess it up too badly. The lift pump on my '97 was leaking at the bottomside of the plunger so it's time to change it out ( the truck has 86,000 miles). To access the pump I removed the fuel...
