Hi, I'm a new Deuce owner, and a new member, my first post!

Howdy, I recently acquired my bobbed Deuce and have been making it road worthy. It appears that my 6th injector (closest to firewall) is leaking externally. My research reading tells me this is probably the fuel return cap. I understand there are two gaskets involved a copper gasket and an injector gasket. I emailed TNJ who have the gaskets available and they suggested I replace the entire injector to solve the problem. This seems unnecessary to me, but I'd love to hear from more experienced owners.

Get a few more opinions from people not trying to sell you something, then make up your mind. I can't understand replacing the whole injector, when the gaskets may be bad.

Yeah I felt the same way. A diesel mechanic friend of mine is going to help me out and we're going to have a look at it. His opinion was that we could take it apart, and have a look, and worst case it would go back together and behave the same way.

From the pics you have, it looks to me like it is the base gasket in the head.......the little copper one between the injector and the head.......if it was leaking from the return cap, I would see wet above the fuel feed line not just low like it is around the orange seal.......I had a leak exactly looking like yours, replaced the copper gasket and made sure to torque the injector bolts down, problem fixed.

Also I would replace the 2 bolts while you were at it, they look a little rusty on the threads and could cause you to not get a good torque spec, they are Grade 8 5/16" bolts, I used zinc coated on mine(that was what came out)....shouldn't cost more than a couple of dollars, but it will make it easier to tighten things up.

Just ask your buddy, it is just a copper crush washer........you might be able to see it in this pic, on the bottom of the injector. Not sure of the exact size, I'll have to see if I have an old one to measure.

Any hints on which TM for this type of overhaul? I got lost reading manuals for awhile there, but I haven't found a source for torque specs yet.

OK, so you want TM 9-2815-210-34-2-2.

In this TM there are 2 sections you will want to pay attention to. Paragraph 4-40 starts on page 4-394, this section will guide you through the entire injector nozzle and how it is adjusted and taken apart(cleaned)

The second section you want is paragraph 5-34 starting on page 5-187, this section will give you the specs on installing the injectors(including the torque specs you need)
