Hey all. A friend of mine has an 01 HO 2500. He's got a drag comp, 240 hp sticks, ps66, walbro 392, etc... Anywho, his injection pump went out and since I work at a local injection shop he wanted me to put an SO pump on for him. I put the pump on, got it running, and it ran good. All of a sudden it started cutting out, surging, etc... Well he found out it was low on fuel. Filled the tank and drove the truck, and everything was fine. I told him to leave the pump wire untapped to make sure that fixed the problem, but he went ahead and tapped it anyways.
Now he called me today and said that the truck was cutting out again, kind of like a bad pump, but also like air in the fuel. The cap on his fuel filter housing is cracked, and there is also a crack on the tank, so I think that he is sucking air into the fuel. He thinks that the pump is bad. He is putting a fuel pressure gauge on tomorrow so we can check that. What do you guys think it is? Thanks a bunch in advance.
