Losing Prime: Fact or Fiction??

[Archive]

I am trying to buy a 96 2500 Cummins Automatic. The old man that owns it says that the fuel line between the filter and the pump is leaking and loses prime when it sets for more than a few hours. He said he called the Dodge house and they said it was a "common problem" with the 96 models. Is this fact or fiction? Is there a greater problem I need to look for?

Barry,

It's probably the hoses that connect the steel lines from the tank to the engine. There are two of them, supply and return. They are kind of a PITA to change so it makes sense to do both of them at the same time. It may be the return pressure valve on the pump. This thing is a spring and a ball to maintain fuel supply pressure in the pump. It's located on the engine side of the injection pump even with the front delivery valve. Check the hoses first.

Barry, It's a fact the return fuel line and supply fuel line develop leaks(rubber hoses). But its fiction that it's only a 96 problem.
There are other problems to look for, as Joe mentioned the return fuel valve can cause bleeding down on fuel also.
Make sure the hose this guy is talking about is leaking. Diesel leaks look similar to oil leaks( collects dirt).
