Ok so my car has a BBK AFPR and when I had it on the dyno last week, it just wouldn't change fuel pressure. No matter what adjustment was made, with vacuum disconnected, it would stay at 45 psi. Now... I'm assuming this means it doesn't work anymore. So heres my real question...

I'm looking at other AFPRs and I've seen a few where they say you reuse the diaphragm and spring and uses a new housing? Like crane and the other BBK. Are these something I'd need to avoid? I can only guess my AFPR quit working because the spring/diaphragm is messed up. Can someone point me in the right direction as to how these things work? Lol Thanks

 

Did you reconnect the vacuum line to the FPR? Just asking...
