I recently found out that the injector line going into the IP was leaking. I can only assume that the ferrule is leaking. It appears that most just replace the line, but me being me I went out and found ferrules. Whether this all works or not I found a good diesel shop in the area. It appears that replacing ferrules is quite easy and normal. All that needs to be done is carefully removed the old ferrule without damaging the line. Use a drill to make sure the inside line size is the correct size. Clean the entire thing including blowing out the inside of the line. Place the ferrule on the line. To crimp it you bottom the injector line out into the IP, and then just tighten it down. It will take care of itself.

I did not get a part number on these, as they were free. The line when I asked how much was it would be more work to look up the part number, so I shut up. If this works though I will get the numbers, and perhaps buy a supply for others.

At the same time I also picked up some of the injector copper washers. The ones used for the ENDT 673 Mack looked just fine. AMGeneral suggested the application.

WOW! Any possible way to get a p/n? I have a bunch of lines, but the ferrules are junk.

Would a Swagelok fitting work?

Its a compression fitting. Not much different than the one on the water line to your ice maker...

The part numbers I will get down the road if they work out, or I will buy a bunch and have them available. I am sure the company would not be too happy if they get all sorts of calls for 10cent parts to be shipped. This is a compression fitting, but is nothing like a standard compression fitting for other uses. Using others I am sure would ensure a leak.

Ethan, did you check the injector?
Metal ferrules on metal tubing often dig into the metal, I' curious about the results here. If it was me, not knowing better, I'd replace the complete line....

I had a small leak at my IP last week...just took a tubing wrench and snugged it up. Should I have replaced the line/ferrule? Snugging it up seemed to have stopped the problem...for now.

The next time it leaks, snugging the fitting up won't stop it. Sounds like getting a handful of ferrules and keep them around.

The original ferrule is on for the duration, I'm afraid, it will not slide off, only turn, the ground through sample shows how it has dug into the steel line.
BTW, this particular ferrule was hardened.
