martinf Posted April 10, 2017 Share Posted April 10, 2017 (edited) Hey all, ive got a midsixties B75 with a thermodyne engine. I needed to use it but after sitting for half dozen years or so, it quit a minute or two after start up. Turns out the supply pump, APE, wasn't delivering fuel. ..and the hand primer wasn't pulling in fuel either. Turns out the pump cavity was empty and, after filling it with diesel (pulled off the primer body and lifted the check valve) I got the hand primer working and pushed fuel up into the injection pump and all was well. But...now after a couple of days it's doing it again.. Won't run and primer pump won't pull in fuel and push it over to the filter. I probably have hunky old fuel, don't you think? I'll empty the tanks and put in fresh diesel and flush the line up to the pump. Any other ideas? Also, are repair parts available for these little plunger pumps? Or even rebuilt units? thanks for any assistance. martin Edited April 10, 2017 by martinf Quote 1965 Mack B-74, dump1974 Mack R, logging w/Prentice self-loaderwww.somewhereonthemountain.blogspot.com Link to comment Share on other sites More sharing options...
