    4010 Roosa master not returning fuel

    Yes mine is mechanical shut off. Mine had a stuck metering valve last time I had to go through it. I had a devil of a time figuring out which way was correct for clockwise or counter clockwise putting it back together. I think I took it apart 5 times before I got it to run, but then it ran...

    4010 Roosa master not returning fuel

    Where is the loading valve? I can usually figure anything out. The first time I went through the pump when it sat because the plungers rollers and metering valve got stuck, it ran like a top. I feel like I did the same thing this time and it just won't run right.

    I don't think it has one. I completely removed the fittingfrom the pump to see if I could get some flow. I got nothing.

    4010 Roosa master not returning fuel

    My tractor sat too long and the fuel system became varnished heavily and needed cleaned. I went through the injection pump a few years ago and had it running great before this. Now I've cleaned the fuel tank, replaced the lift pump and filters and went through the injection pump and resealed and...
