I would invest in a regulator.

i dont know what brand fuel pump it is but i know that it is a 255 and i dont know if my diaphram is bad in the one i have or if the gauge is bad. I also tried putting on a stock fpr and it ran worse

do you have the high pressure walbro?

get a adj. fpr and tune it down.

i have a aem fpr and it will go up not down no matter what i do i think fuel was added through the ecu because the guy i bought it from had it tuned at adrenaline and they added more because of a vaccum leak and he fixed the leak and it shot the fuel pressure up
