    just got my new glow plugs in today and trying to reinstall(had trouble getting old ones out too), they don't seem to want to go down into hole, any advise?


    I'm a little afraid to hammer them in, not even getting to threads, could have taking the injectors in and out knocking something out of whack that needs to be indexed to get these boogers to line up?????

    well got the new filters on the machine today and it seems to be running worse


    even cleaned out the stupid tank

    number three when you crack the line with engine running at injectin pump seems to be spitting some air with or frothy with it compared to the others, also noticed a drop in fuel pressure now under load on the main gauge

    Still air in the system?
    Or it sounds like #3 injector "valve" could be allowing compression back into the line. Does it cause a similar difference in the idle quality as the other 3 when you cut them out one at a time by loosening the lines?

    well I fixed it, sort of:-)

    Rigged up a Holly red pump inline just below tank and the machine has tons more power, it's dark didn't run it very much but was able to cut the brake in second gear which it has never been able to do

    little sucker blew off a jerry rigged hose near the pump, what a mess kinking line and stabbing that sucker, gonna tighten hose clamps down i'm afraid this pump could make a pretty good leak and the machine still run just fine, I think it blew out a gallon of fuel before I could get to it!

    Does anyone know how many PSI the low pressure pump is supposed to keep in the tank before the high pressure pumps and the specs on the PSI for the high pressure side?

    I've got a dummy guage........red or green, also hoping not to cause problems by putting to forcing to much fuel to that first fuel pump, I guess if it doesn't leak then it is OK.
