Please help me identify this line and what I need to replace it

[JROCK5.9]

Hey guys I'm just wrapping up installing a new radiator and mishimoto trans cooler on my 2004.5 Cummins and I started the truck went to fill the coolant and saw a diesel pouring out of what I noticed looks like a fuel return line? I will try and post photos but I wouldn't even know where to begin

Maybe this?

Was that the one with the quick disconnect going back to the tank?

Sent you a PM with a diagram.

Not sure what that is but seems to match the photos, still looking

Good point, could be the tank return line, I dont remember how it was routed and dont see it in the srvc manual

I would be more concerned about a major structural failure while driving it. You must live in the rust belt?

I’ll see if I can find the part number when I get to work.
Suppose you can get that out of there and not ruin the plastic quick connect? If your luck is like mine then probably not….

I'm going with # 11. This would be the supply line connection.

If it connects to the fuel filter housing this is the one. It's kinda' hard to tell from the picture...

Cummins Part # 3973915. I'm not blocked, if it were RAM only I would not be able to put it into my order.

The PDC in Harrisburg Pa shows them on hand.

The tricky part is going to be saving the plastic quick connect. It can be done with patience. I have saved those time after time, you have to get the crap flushed out of it so the plastic release tabs will squeeze inward. PB Blaster or WD-40 will do it.

For the benefit of all, the part he needs appears to be the return line in post #5. The Chrysler PN is 5093088AA and it is available from the dealer or Geno's.
Quick disconnect repair kits are available at most Napa stores.
