Hello guys. Had the fuel injectors rebuilt on my ford 1500 tractor not to long ago (prior thread). 2 cyl. Shibaura Diesel. I put the bottom seals in and tightened the bottom nuts as tite as I could. Been running it every 2 or 3 days since and when I recheck them before starting they always tighten up another 1/10th of a turn more or less.
Yesterday after putting new fuel hoses on both sides of the filter I was cranking on it to vent the lines. Then I noticed fuel around the base of the nuts and I hadn't loosened the compression fittings on the fuel lines to bleed those lines yet. I tightened the nuts back up and had to loosen the banjo nuts to rotate the vent lines back around and bled the lines off. Ran it a few minutes and looked at them. Noticed that it looked like one was showing a little fuel coming up from around the nut on one cylinder. Put the wrench back on it and got it a hair tighter.
Ran it for an hour and took a tour of the creek bottom and it was ok then.
So I'm wondering why I need to keep tightening these down and if something else is going on with the seals which are a copper type washer. Thanks. Will check them again today.
