Hi I got a 2002 2500 quad can and my fuel return line is leaking after the T by the motor. Is that a push on connection and if I buy the line from the T back will it run all the way to the tank? The images on Chrysler website are vauge

 

Yes, it's one long line with a push lock connector on each end. Is the line itself leaking? Or is there just fuel everywhere Underneath the truck?

 

It's leaking by that pushlock then. Bad seal I'm guessing. Iine looks clean. It's a constant drip now and with highway speeds I'm guessing it's just traveling down the line with the help of the wind. Can I just get a new seal to put in their or do I have to replace while line?

 

The T looks fine just after it it's leaking. I did install a new pump with an airdog frp 100 I'm wondering if my pressure is to high. I uused my glowshift fuel pressure gauge to set pressure so I'm guessing I'm pumping too much

 

Yes you can go to a parts house and get a seal the same size and put it in there, to get it out use a skinny 45 degree pic.
As far as too much fuel pressure; that will not cause seals to blow on the return side the what you need to be concerned about with to much fuel pressure is blowing the seals out of the pump.
If I were you while I was working on it I work tighten up the bango bolt on the back of the head, it's a 17mm. Every once in a great while the need to be tightened, just don't break it off in the head, make sure it's snug. And also the T has small rubber seals were the lines go into it. You can take it off check the seals, clean the T and put it back together with thread tape. That's just if you want to make sure.

 

Ok I will check it out more now I have time

 

Culprit was home rusted on bottom line Got to replace all way to tank. It was under push clip
