Well a little change in plans on this. I finally got a proper set of line wrenches from napa, and removed the line. It looked to be in good shape, so I cleaned and reinstalled it with no more leak so far. The fitting is bottomed out though, so if things loosen up again I will have to replace it.

Bjorn I was not able to remove the injector as the tip must be stuck in there with some carbon on it. I will have to putt together some sort of puller in the future. The supposed fuel leak on top of that injector I am now thinking was spray from the IP to injector line connector. I had gotten some considerable spray a time or two on the way back from Thanksgiving. I resealed the T fitting though to be safe, and am keeping an eye on it. The engine has been running smooth through all this. The diesel guys I talked to said that the ferrules can usually be replaced, but if bad the line can usually be cut down a bit to allow the ferrule to sit on fresh tube. There were also not happy with the radius of the bends on our lines.

If someone wants to try to replace a ferrule or two on their leaky truck I will send you a couple. Otherwise until I develope another leak a ferrule install is on hold.

Ethan, after you get the two "hold down" cap screws out, just give it a little tap and it should come right out.

Yeah I tapped and twisted and was about to pull out a bigger hammer before I realized what I was about to do There is just not a lot of room to work with though. I am figuring a slide hammer will work.

The prybar works well also.

I didn't mean to sound like a water compression fitting would work. Was just trying to point out that the principle of how it works is the same as other compression fittings. You slide it on the tube and when you tighten the nut down it compresses and no leaks.

Well a bit of reversal here. Guess what? My lines are leaking again! Anyways I took the line off and gave replacing the ferrule a try. I found that the ferrule are a hard steel that was not able to be cut with a hack saw. I ended up using a bench grinder to remove it with LOTS of care as I did not want to so much as touch the line itself with the grinder. I found pinching the ferrule in a small vice grip helps to push the ground sides away from the line. Grind carefully until you see the slightest of cracks in the steel then turn it around and do the other side. It should split off with a slight pinch of the grips. I found a similar gouge line as Bjorn did caused by the ferrule, so I cut the line down to that line. I faced the line after with a fine file, rounded the edges, drilled , and then champhered the drill hole too similar to original. Then I cleaned the entire line including blowing out the inside of the line. I won't know until the morning if things stop leaking, but it looks good so far.

nattieleather I tried to be a bit clear there after just imagining someone going down to their plumbing supply store for a ferrule

Just my 2 cents here. All injection line on nearly all diesel engines are the same length, tuned as some might refer to it. This is done to ensure proper timing. All be it a slight difference, a little can be alot for a diesel.

Agreed, the lines are identical in length.

Ethan, why not replace the line, there are plenty around...and do check the injector.

I have put some miles on the repair this morning, and there is no more leak! I still have to go back though to adjust the line to fit back in the rubber antivibration holder. The diesel shop suggested that the about 1/4" removed would not make a difference. She is purring again. I am going to get my spare set of injectors all cleaned, and then install them on this truck soon.

Yes I know replace replace replace. This is a viable way to replair a leaky line, and is something that could be done in a pinch on the road with a hacksaw, file, drill, cleaner, and a ferrule. I will be buying a set of injector lines for my spares stach though.

I know this is an old thread but it won't hurt to ask, does anyone have a source for these ferrules??
Thanks in advance
