Fuel leak

[Mopar1973Man]

Personally, I would just ditch that chunk of line and get some quality diesel fuel line and two hose clamps and just replace that section. The piece of line from the bottom tee connection to the frame rail going back to the tank is just plastic. It firms up of the years of 140 to 160*F fuel ran through it.

My 2002 has a plastic disconnect on the bottom of the tee on the return line. Mine was leaking, and I got new plastic inserts at NAPA. IIRC, they are 3/8.

[Mopar1973Man]

Could you list the part numbers if you know them please. @greed

[greed]

Unfortunately, I did not save the package. I checked my stash of inserts, and I believe it is a 5/16 insert. I checked the Dorman website and came up with Part# 800-005. Hope this helps.

[James merritt]

Greed, are you saying you repaired the disconnect?

[Mopar1973Man]

Well, that is part of it that is just the clip. 

[greed]

Yes, I replaced the insert and the leak stopped.

That sounds like the easiest, the disconnect isn’t in a place to be able to disconnect it anyway. Is diesel fuel line different from regular fuel line. Piece of hose and two clamps sounds great compared to yesterday.

You just need hose that is compatible with diesel fuel. Some hose is not.

[greed]

I was able to get to the disconnect from under the truck. IIRC, it was a pain, not much room, but doable.

It’s 34 degrees out and I have my 5 foot piece of hose and 2 clamps better now than never.

What about removing the Tee and relocate so its easier to get to? Using hose clamps, flexible fuel line and a brass barbed Tee, it seems  best to locate the Tee down low on the frame where it is easier to get to. Anyone see any problems with this mod?

Prayer the rubber hose never kinks. Sure hate to to see what pressure build up will do most likely blow the front seal of the VP44.

[JAG1]

Huhh! My fuel line hose does not kink it is high pressure diesel fuel line hose. It expensive but cheap compared to what it is and how long the stuff lasts. It does not like to kink.

So @Mopar1973Man has kinky hose and @JAG1 does not. This sounds a bit strange.

Hahaha...there's so much that can be said here.  But since I'm the new guy I'd better zip it... ?

All joking aside... why not move that problematic tee? There is no high pressure and my fuel returns dump into the fill necks on both trucks.  so no big deal right?

 

It is my estimation that tee is a poor location when it can be easily moved for servicing elsewhere.

It is my estimation that tee is another rope you into the dealer kind of design when it can be easily moved for servicing elsewhere.

I dont see why you could not do it. Just do it in a professional manner. Me, I aint going back in there till she starts leaking again.

 

 

I see how you are when its not a chicken joke.

Wow,

all good stuff.

you just don’t know what you don’t know ! 

[James merritt]

I read the move the T after I was done. And the T maintenance was for knot anyway, I spliced in a piece replacing the disconnect, and believe me I don’t have a clue why they call it quick. After 15 minutes no leak, better mileage here I come. Thanks everyone. It will be a day or two before my hands recover.
