Lol, I try to convince my wife it benefits both of us, she never seems to see it that way.

That's the filter/regulator I run. The extra 1.5psi shouldn't matter at all. It's just set at a true 4 bar rather than 58psi.
I got the -8 orb version.

In the UK 4 bar is almost exactly 58psi :confused:

I was able to hook up a Fuel Pressure gauge I could see from the car. When I hook the guage into the line right after the Corvette FPR/Filter, I get 62 psi. Itís dead on 62psi while driving and at WOT. 

When I hook up the Fuel Pressure gauge to the end of the fuel rail (the end of the fuel system), It is also measuring 62 psi consistently. Under WOT, it drops maybe a psi or two and recovers and builds maybe an extra psi to 63-64psi or so as I lift the throttle.


What fuel pump are you using?
