Message: [QUOTE="Pure Evil, post: 665567, member: 5003"] **UPDATE** So the saga continues but as of right now this story has a somewhat happy ending pending a resolution with Air Dog which I'm sure will be anything but easy. The pump I paid to have over nighted (not the company responsible for a defective product) arrived Tuesday and when I put it on the truck yesterday afternoon guess what? Same damn thing will not build pressure. So two new pumps have now failed to build pressure out of the box. I know what you’re saying at this point. It must be on my end no way it’s the pump's fault both times, Hell I even start to question how did this all go so wrong on such a simple swap? And in disgust I walk away from the truck. This morning (once the urge to see what color the air dog turned while in the bottom of the burn barrel sub-sided) I decided since my old pump builds pressure but once it has been run for 5-10 minutes the electrical side goes out why not take one of the new motors that will not build pressure in its current configuration and put the new motor on my old pump that seems to like the old base and see what happens?? One turn of the key and I have fuel pressure!! Over the weekend I came across a post I believe on a dodge forum about a misalignment of holes from a new pump to an old plate that would cause this suction issue.. When I talked to our friend Josh Monday he stopped me mid-sentence knowing exactly what I was talking about and assured me that couldn't be my issue as that had been corrected 5 years ago.. Well I am here to tell you that is NOT the case. In his defense when this first came to my attention Saturday I put a light film of grease on the O-rings of the old pump then did the same with the new pump to compare mating surfaces.. They looked to be identical on the original base, so I moved on in my diagnosis. But THERE IS A DIFFERENCE SOMEWHERE in the 2 pump housings I've just received and the one that came with the pump originally and visually I cannot for the life of me tell you where. I did find the old motor to have one burnt brush which seemed to be its problem. So the truck runs which is the high point of this story now I need to call my dear buddy Josh and see what he has to say about all this, and if I can recoup any of my money from fixing their problem.. I'll let you know how this turns out.. [/QUOTE]
