I figure I would post the problem I've had with the 94-98.5 lift pump I put on my 1st gen.
First let me say I don't know of anyone else that's had this problem.
I purchased a 2nd Gen lift pump directly from Cummins, I didn't purchased a cheap aftermarket one.
I also had my pump professionally rebuilt and never even ran it with a 1st Gen lift pump.
From the start fuel began leaking out of the of the EFS where the threads come out of the top. So I replaced the EFS and it still leaked so I tried another EFS and it still leaked and I don't mean a slow leak neither. I was goes to put a threaded plug in place of the EFS but am worried something else could go wrong so I am reinstalling a stick lift pump.
Does anyone happen to have the fuel line that goes from the top of the lift pump to the motor?
