[QUOTE="randy4354, post: 74995, member: 9991"] That looks like to be right Tazza because from some other articles I've read guys are using some basic fuel pumps on 200 - 300hp diesel trucks with no issues. I did a check on all the lines and fittings, everything there seemed good. Couldn't inspect the fuel tank check valve because the lines disappear back between the lift arm and the lift arm cylinder. The only spot where I found and signs of leakage is at the injection pump. I tried tightening the fittings for the in and return but it is really difficult will the engine is in the skid. Also the fittings for the lines going to the injectors look wet, but they were all tight. One of them I couldn't get a wrench on. So I installed a inline filter which has a hand primer pump on it before the mech lift pump and pressured the system before starting with it. I needed to pump 60 - 70 strokes to feel the system firm up but the starting was better. It would catch after a couple cranks but still seems like it not getting enough fuel, it would be a little rough and you would have to back down the hand throttle to get it to smooth out. The fellow I bought it from said he always had the hand throttle wide open when starting, but I don't think that makes any difference when starting, should it? Also the results are better but still not the way you would like the skid to start up. Any suggestions? Thx Randy [/QUOTE]
