well with the valve in place and it is pouring fuel out, then I would replace with an oem one. Some people say you can just cap it, but why not get an oem replacement for about the same price and give you a little comfort. Capping it some say causes excess pressure in the fuel rail and can destroy things, be safe and go with a replacement.

Hi

Could some of you CR experts give me a hand or better yet, your knowledge? The CR pressure relief valve has a history of failure. I have been looking on the web for a few days to find out why.
This is what I've heard. (1) The spring weakens and looses its force (2) The seat and poppet become etched (3) The poppet tip breaks off
What have you guys experienced? Have you done any testing on the CR relief valve?

Thanks for helping me out.
