Well , I went down and bought a fuel pressure gauge which solved the problem . It's barely putting out 15 pounds. Does anyone think that this is why my power has been dropping ? I was thinking that , possibly , I was just getting used to the output of the engine . Do fuel pumps generally fail gradually until the engine just can't perform or do they just fail all at once? I'm wondering if the right pump will show an immediate improvement in performance . Thanks again to Red for the timely and correct diagnosis.
