This is a long story, I will cut it down. My vp44 went out. I knew nothing about the pump, took it to a shop, they replaced it. Two months later I am getting the hard start stuff when hot so I go searching on the net. Find out about the lift pump problem. I got a pressure gauge and screwed it into the top of the fuel filter housing and it read 5 pounds and did not move when I increased fuel. Took it back to the shop and they said the fuel pressure was fine. I put a new airtex fuel pump on and I put a fuel pressure gauge on it like you suggested on your web site. I know it isn't a pump that you recommend but it is what I could afford and now I could monitor it with the fuel gauge. When my truck is hot 75% of the time it wont start. The fuel pressure gauge will be over 20 pounds up to 22 to 23, when trying to start it. So I was going to try this fix and needed some help. I have done the muffler delete and am saving my money for the big honking air filter. I have the auto trans and the mileage hasn't improved much at all. Thanks
