I guess it really depends on what he means by fading. I assumed he meant
when he was driving, it would slowly drop pressure as rpm/load increase
which could be a stuck FPR (if it was a one-to-one function). If that's
not what he meant, and it the pressure just floats around at the same
rpm/load then Scott's right, it couldn't be the FPR.

An easy way to check is unhook the FPR hose @ idle with the gauge hooked
up. Does the pressure go up?
