Hello Orange Family,

I was discing with the 8050 tonight, when a huge cloud of white smoke came billowing out from under the hood. Managed to find a hole in the number 5 injector line kist below the ehxaust manifold. Hot manifold, and good flowing fuel, = lots of white smoke.

Now I need to repair. It was getting dark, so I will work on it in the light tomorrow. I am thinking of bending my own fuel line to replace this one. It has been a while since I had one of these apart. I forget if the flare at the end is single, or double. I know I have some new rubber washers that seal the line under the threaded cap.

In addition to the type of flare, does anyone know the diameter of the line? Can I Get fuel or transmission line from the store to work?

In case it matters, it is the set up where the lines all go straight up from the pump, then cross over and above the exhaust manifold, not the other one.

Thank you,

John

Isn't it just a special ferrule under the nut?

I could be wrong, but I don't believe that injector line tubing is just "run of the mill" tubing that you get off the shelf and put flared ends on. Think it's much thicker then that. Darrel

Injector lines are very special, thick walled tubing. The lines are a specific length and must be exactly the same length as the other five lines. They must be bent smoothly with no kinks. They must be secured so they can't vibrate or move around or rub anything else. I believe the ferrules on each end are welded on, not crimped. Buy a new line from AGCO if available. If not, buy a whole set of lines from a used engine.

There are two different style lines they used as well. The later style only came as a whole assembly which is discontinued. The early style. Shows they have 5 of the #5 line in Batavia.

the ends on the Ermeto like AC used are just crimped on ferrules, though special for the purpose. AGCO # is 74501149 for ferrule, and 74504409 is the nut. Making an injection line is not something just anyone can, or should do. I get lines from Scheid in Effingham, or Fair Valley Performance in Sauk City Wi. Usually you have to send in the old one to copy. That material is very tough to bend, and bend correctly. I had Scheid make me #3 lines for the early style on an 8030-8070, and have 1 left. I'm no help on #5 lol!
