As most of you know, I recently had a new VP-44 put on. Last night, the truck started bucking under heavy accel. I ***** footed the truck home and had no further incident.

Popped the hood and found diesel laying along the block under the injectors and the fourth one from the front had fuel laying up in the retaining nut for the injection line.

My question is how tight are the nuts supposed to be? I took a wrench and tweaked the leaky one. then tested the others. I could tighten one of them with two fingers on the wrench.

I didn't want to really crank them down, fearing that I might crush the line or something. So my question is how tight can I make them?

I'm going to easter dinner, so I'll check back later tonight after dinner.

Please let me know your thoughts on the retaining nuts that hold the lines on the injectors.

Thanks, Mark

Guess I'll have to break the news to my wife that I need new RV275 injectors.

Seriously, any info would be helpful...

 

Just tighten them up and then start the truck and crank them until they are sealing. You are right it's easy to over tighten them then you will need new tubes to go with the rest of the new parts.

 

Tell her you need some 150hp injectors to make the truck run

 

Basicly just give them a good snug, Its more of a feel thing! There pretty tough but its not a good place to break somthing! It's a flare fitting so its not really about the torque!!

 

Thanks for your responses. I appreciate all the help.

I will snug them all up a bit. Maybe not mess with the ones not having a problem.
I'll let you know what happens.

Thanks, Mark

Still getting wet, around the fitting. I kind of tender footed it to work today. I'll try on the way home to see if I can get it to leak again.

Thanks much, I'm going to close the thread.

Later, Mark
