Re: Injector ?

If it's not coming from the top of the injector pod, it's likely the o-rings that get installed along w/ the injectors. If I recall correctly, there's also a thin, narrow backup washer for the larger upper o-ring.

Re: Injector ?

I have turned on the pump without the car running and there are no leaks I have let it run for a couple of min just to make sure there was not a slow one. It will only do it when the injector is working.
