Hi all, New here and need some help. I have a 1989 dodge diesel and have noticed a fuel leak. Looking at the pump from the driver side fender I see a small rubber overflow tube?? on the backside of the injector pump. This is on the right side of the pump or you could say the firewall side. I removed the rubber tube and I can now see (with a mirror) a square silver piece with a brass middle with a small pinhole size area in it. This only leaks while running. Can this be tightened? Does it need replacing? Expensive fix???? HELP!

I hope I described this in a way you can understand!

Thanks, Heath

The problem would have to be internal. The piece you refer to is a vent, and there shouldn't be fuel in the area behind it. Tightening it won't help. Hopefully someone else can tell you what the actual repair is.

Most likely culprit is the AFC pin's 'o' ring. Lemmie go look at mine to see how much of a pain it is to replace.
BTW--welcome to DTR!
