VAFC and b&m fpr question
soon to be putting a vafc in my car and i have a b&m fpr but i have no gauge. will the vafc tell me the fuel pressure?? should i bother buying a gauge or can the vafc tell me everything i need to know?? thanks...

if you have a place to mount it on the rail make sure you get a liquid filled gauge then...the non filled one have a tendency to malfunction because of engine vibrations
how would it be more accurate? if youre seeing pressure drops in the fuel pressure because the guage is mounted somewhere else then you have other problems not the gauges

Agreed, Fuel pressure shouldn't really drop at anyplace along that line.
Also, get your car on a dyno, check to see your a/f readings throughout the rpm range. You shouldn't see much of a drop, if it looks like your losing fuel along the chart get a FPR and guage, and raise it up a bit. Might be better to use the VAFC.

if your car is running temendously lean then it would seem that the FPR is not the solution but rather a higher volume fuel pump is need and now with the FPR you can bring the pressure down to more normal pressure levels
AFC is also an excellent suggestion by cronic espcially if you want to fine tune the A/F curve
and Dyno time is always a must for tuning
