This is where it's a problem for me because some guys say one thing and others say another. I haven't personally experienced any of this, so I don't know who's right. The Corvette would be the "returnless" system from my understanding, so I would expect 58PSI.

I did already test another flex fuel regulator, so I am aware that's easy. It's just that I can't see spending a bunch on one just to test when I won't use it after that. Is a generic $10 unit reasonable to test with?
