I’m leaking fuel from a plastic line connected below and to the right of the fuel filter. I took out fuel filter but can only get one hand by the leak. I’ve tried getting at it from underneath and can’t. I took the wheel well plastic guard off and there is no room. My only option that I see is cutting the metal out of the wheel well big enough to get my hands at the problem. Would there be an access through the fire wall I don’t see. I think I put my fuel gauge in the wrong place because it aways maxes out at thirty and never goes lower. Besides the fuel leak I’m worried about my injector pump because my truck aways started right away and now I have to crank it multiple times pumping the petal to get it going. And that seems to me like no fuel. I think the plastic line that’s leaking might be a return to tank line. Could all the extra cranking to get it running harm my injector pump?

I have two of these trucks and often wondered how I would get to that Tee if it ever leaked. I often think about making a plank scaffold that allows me to lay belly down over the engine. Maybe getting some 2x10's or 12's with four step ladders used for support. I would hate the thought of someone doing all this though and find it did not work out at all. Maybe something simpler perhaps

Talk to nasholes, they'll set you up. And that's all I'm going to say.

I moved all the wires out of the way and can at least see the T. Without running the engine I don’t know which line was leaking? The lines look kinda fragile and I don’t know what parts to actually change. Any suggestions? I’d like to have necessarily parts on hand before I disable the truck. Thanks for your thoughts.

 

First off I notice something that others didn't. You deleted the stock fuel filter can and fuel heater then proceeded to leave the intake manifold bolts out. You are taking a big risk of blowing out the intake gasket. Make sure to replace those bolts.

 

Now looking closer you need to power wash that engine off with some good degreaser and inspect your injection lines. Some that hardware looks marginal at best. 

 

As for the Vacuum lines. Kind of goofy layout personally. One of these days I'm going to re-do my set up and use mostly air brake tubing and just small pieces of rubber vacuum hose. I hate the idea of everything just hanging there on the driver side. Most of this stuff could be routed to a fender, along the frame etc. Vacuum wise the only thing on our trucks is HVAC, Cruise control (auto's), CAD (early 2nd's), exhaust brakes (optional). 

I’m not sure about the fuel filter and heater. I took out the 2 bolts for fuel filter can and it’s just hanging off to the side. When it stops raining I m going to work on it, but not sure what I’m going to do. I don’t know where the leak is, just that it follows the line down and drips. I’d probably blow half my lines off with a good pressure wash, but yes it needs one. I bought the truck new and pretty much just worked on stuff when it broke.

If your close to a source while its raining go down and get the correct size sealing washers. I like extras hanging on my tool board. I think sizes might be all the same but that's what you should make sure of, that your getting the right ones.

I found the link to repair and replace the tee. Thank you very much. I will order some parts. Since I don’t know which one leaks I should just do all.

Whew! I thought you ditched it outright... Still in all a good power washing would help that beast. Just remember to put the fuel filter back on and bolt it down. 

Thanks everyone, I ordered parts from Geno, I will see how it goes.

My injection lines have lost a lot of the goldish color coating that was on them when new. I had to replace injector line #5 back when the end blew off of it. The new one fro. Cummins did not have that coating on it. Appears just to be the bare metal.

 

@James merritt happy you found the parts and yes do them all. If one is leaking the others are not far behind. Did you get some sealing washers? A few spares are good to have on hand. They should fit the VP banjo too.

I bought 4 banjo washers and only 3 of the T washers they were 10.95 I think so didn’t get extras. I put it back together so I have wheels and it still drips. Thanks for the thread I didn’t know where to look for parts. Dodge never has what I need in stock anyway.

I should be in the washer business my bill was 51.80 for seven pieces.

Take a can of brake clean and spray down the area with the engine hot so it evaporates fast. Now idle the engine and watch for where the fuel is coming from. 

 

I just got done with the same issues. Between the return rail at the back of the head and a few loose injection lines I was dripping off the rear of the head and running off the bellhousing. The brake clean will make it clean and dry and allow you to source out the fuel trail and where its coming from. 

 

I know its frustrating to have fuel dripping off the engine. 

I will get a couple cans , it’s following the one return line but also dripping off bellhousing. Thanks

In the two drawing of the T in the fuel components one looks to have a steel line after the bottom of the T connection, the other looks to have a plastic something. I have the plastice thing that’s looks like a quick disconnect. I think that’s where my problem is leaking from. I can kinda reach up to it a feel  the connection but can’t get it to disconnect. Now my guess would be take bottom line bracket off block and unscrew bottom nut and cut line down low where it’s easily accessible and splice in a piece from the disconnect down,, after all this is a low pressure return line isn’t it.

Definitely not high pressure. 

Is it possible I have a quick disconnect on bottom line off T. I bought truck new and I don’t recall doing anything to that fuel line. Does anybody know what size that line is? I think it’s steel with plastic coating on it. I have to go get parts before I can take it apart. And leak a gallon of fuel. Thanks for all the help I’m getting.

I did not have a disconnect on mine just the metal metal fuel line. I think it is metric but what size I dont know.

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.
