My 1982 2GM
had a small diesel
leak, around the fuel lift
pump, when I fired it up this spring. Looked like the pump was leaking, as diesel
was dripping from it. However, it turned out to be leaking at the banjo fitting on the output side of the pump. I tightened the banjo bolt about 1/8 or 1/4 turn and the leak stopped. Worked fine for 2 months. Same thing happened again, so I tightened it again. Worked fine again for a month or so.
Now doing it again, and I am afraid to tighten the bolt anymore, for fear of breaking it, etc.
Do you think that a new set of copper washers will fix it? If so, what size are they?? My Yanmar
manual had pictures of them, but i could nbot find the size!
Are they available / common at auto parts
stores, or is this a dealer item?
