Just had my pump rebuilt (74 5000 D Cav) and one fuel line is leaking at the fitting. I have it as tight as I can get it and it still weeps a little. Any ideas , need to replace line?

I've had to swap banjo fittings before to stop fuel drips. Sometimes the line end will crack just inside the nut and line needs replaced. Those banjo bolts need to be REALLY TIGHT to get those washers to crush for a good seal also. Sometimes loosening/tightening line nuts five or six times will work too.

Itís not the banjo fitting it is a fuel line itself, I got it as tight as I possibly could. May have to replace the line or take it off and clean the fitting.
Thanks for info

I'm not sure but there may be a seal in there that didn't seat right...another cause could be that when the line was put on that a small piece of dirt or sand got in... I'm assuming it didn't get cross threaded . If this line was replaced inspect the flare to make sure that it was done well ( no cracks and a good full seating flare)

I had this problem. I put old washers back in. Problem solved.
