    Source for primer pumps?

    My 1984 6.9 has an electric fuel pump in line to prime the system after changing filters or getting air intrusion from sitting too long. I have owned the truck for 25 years and have put several in after the first died a dozen or so years in. Each new one last less long than the previous and...

    7.3 IDI won't stay running

    I had a similar issue with my 6.9. It turned out that the cheap shutoff solenoid that I had installed, swelled up and was preventing the mechanism in the top of the IP from moving back and forth correctly.

The coil must be getting hot and binding on the shaft that is supposed to slide inside it. I ordered a new solenoid and will attempt to replace it...

    Won't shut off when hot

    I have not touched the IP since timing it and this just started happening. The hotter the engine, the longer it takes to shut off. Are the valve surfaces metal or rubber?

    Won't shut off when hot

    I have a 1984 6.9 and when it is hot, it won't shut off. It has a turbo cool-down thing that is supposed to keep the engine running until the EGT drops below a certain level so I first thought it was that but its electrical and the beast kept running even after I disconnected all the wires to...
