Default Anybody here install their own VAST fueling kit? I have a question.

The nuts that they give you to serve as spacers for the fuel rail, did you put those between the fuel rail and manifold? If so did you notice that your injectors are not seated very well and you can turn them by hand?

Mine not only can be turned but you can see the area where the injector is seated into the mani get slightly wet with fuel and when you shut off the car you can see little air bubbles aroudn that same area. I don't think that is right.

Default With different fueling kits, using 60 #er's I have been able to turn some of the injectors even tho

they were fully tightened down, but as far as leaking , thats never happened.

When you say you can see down into it, is the O ring fully seated inside, so that you can't see any of it?,

Maybe you don't have the injectors in deep enough either in the manifold, or the fuel rail..either that or the nuts are too big.

But I gues you can tell by whether all of them are wet as you describe, or just some of them. If its just some of the injectors I would think maybe they arent fully seated.
You have to really press down hard on that injector to make sure it sinks all the way into the fuel rail and also the manifold.

Default Yes, they go between the fuel rail and manifold...

did you get the slim green injectors or black injectors?

You shouldn't have any seepage past the injector through the injector bung. This is not normal.

The injector is allowed to rotate though.

If you want, just email me and I'll walk you through it. I want to get to the bottom of this seepage you're seeing.

Default Fuel seepage is no good. You should check that your old O-rings didn't accidently come off of the..

old injectors and stay seated in the fuel rail. If that happened you would have an o-ring inside the fuel rail not allowing the injector to seat properly.

Default No leaks from rail. Slight wetness around injector going into mani and I don't see

I don't see the o-ring. Everything is nicely in but the ease at which I can rotate the injectors is a slight concern. Thanks for everybody's help.

That did not happen with mine. Did you use some lube on the o-rings?
