My car is doing the same thing with a leaky IP. Does it loose prime as soon as you shut it off or only after sitting for awhile?

sounds like the everloving air leak after breaking lines free trouble. I would go back over all the lines and refresh the copper washers and make sure they are sealing up correctly. Sand with 400 grit paper and oil then heat them.

so i belive its just an air leak in the return, i dont have one of them fancy caps for the one end of the injector that goes no where so i took a piece of return line and screwwed a screw in it and yea it was leaking diesel there and i could see bubbles goin by it after i shut the engine off, so now question where do i find a plug for that.

Yeah its not under that much pressure. A good piece of hose with some kind of stopper in it will work just fine.

jpedro if you have a local WorldPac parts retailer/distributor
they keep those in stock for about $1 each.
Any VW or Mercedes dealership should have them in stock too.
I always keep about 4-5 on hand at all times.
BB in a piece of inj return hose will get it across the curb for sure.
Maybe even put 2 in there. lol

Or if you just find a piece of rubber I'm sure you could gouge out a little bit and shove it on. I had to reuse mine off my other head, and it broke half way down.. so I just drill out a little deeper and it seals with half a plug.

I was out of return caps, so I shoved a piece of ground down framing nail into a piece of jumper hose. Been there for nearly a year and no leaks... I got some caps about a week after, but I figured why bother pulling it.
