I was able to snag a new Bosch fuel pump for my Tj. After installing it I found out it dribbled with pressure. Dud! Had to put my delphi back in. Now I'm in the process of trying to clean it up so I can return it.
 
That is probably what carid is hoping. They sent me a ups tag. I told them gas had been run through it. They basically said so.
 
I swapped my old pressure regulator out with the new one just to rule that out. Didn't make a difference. So I figured the pump is weak. But I noticed while running vinegar through it to clean it for shipping the cylinder filled up and ran over. I wondered if the pump is good but a blockage or bad o,ring going from the pump to the regulator. Has anyone ever taken one apart? I really would like to keep it if it's something simple. I have an old pump I could look into.
 
I wouldn't run a pump after putting acid through it even if I did find some simple solution to what the problem was. Once you put vinegar in that thing, she done.
