OK heres the scoop, I have pulled the pump I installed last fall only to find out the internal fuel hose and nipple had come loose. Thinking I had to change or rebuild this pump I got a free rebuild kit from the vendor I bought this pump from last fall. I installed the kit and thought I would epoxy the nipple to its seat to prevent this from happening again. I re installed the pump. This time it blew the hose off from the nipple, so I picked up some hose clamps and re installed the pump again. Now it blew the hose and nipple off again. I don't understand what is causing this problem, any ideas....???? The fuel filter is new and when the truck runs it runs fine,no hesitation. Could this be a fuel pressure regulator issue or something similar????

Have you ever tested the fuel pressure?

Get a oem type fuel pump module. They come with the hole works.
And remember dealer oem parts only hurt one time.
That aftermarket stuff can bit you in the rear many times.
