Hey guys, on another post you helped me get my fuel pump on my AC 185 rebuilt. I cleaned it up and put a kit in it because I just can't afford to send it in. Anyways, all has gone pretty well. When starting the tractor the first time it took a lot of pumping on the manual primer to get fuel to the ends of the lines. At one point, to make sure I was getting fuel through the pump at all, I loosened three of the fuel lines on the pump. When I saw fuel come out, I tightened them back up. Soon after it started and runs really good. The problem is that those three lines refuse to seal! Fuel leaks around them badly. Almost like the crush washers were too hard or something. I took my old crush washers and heated them up glowing red and let them cool slowly to soften them. On these three I've replaced the crush washers with these softened ones but they still leak. I also have one fuel line leaking at the injector, though the line is tight. Like I said, the tractor runs really nice. No misses that I can tell, but I'd like to stop the leaking, of course. Maybe I goofed something up and accidentally turned up the fuel pressure or something. I don't know. Any suggestions by you smart guys are most welcome! Thanks!
Also, I understand why they didn't use O rings on these lines because of the pressure, but why can't soft copper or lead washers be used? I would certainly feel more comfortable with the sealing capabilities of a soft lead washer than a steel one.
