No you can't. Unless you get a peice from a company like AEM who has adjustable fuel pressure regulators. And how do you know that you fuel pressure is really high??? Do you have a gauge?? What is it reading??

its reading at 40 psi

At idle or at WOT??? Standard idle pressure for a b16a is 40-42 psi. WOT should be around 44-46 psi. What kind of car do you have?? What engine?? You've got to provide the right information to get the right answers.

Yeah I'd say leave the fuel pressure alone unless your going to raise it due to performance modifications and you need more fuel. Maybe your poor fuel milage is due to a heavy right foot!!

yea i was going to tell him the same thing. if he has a stock FPR and it took a shit. without a FPR...with high fuel pressure the car should be running extremely shitty. but i agree the poor fuel milage is caused by heavy foot or incorrect tire pressure, or lack of a tuneup in a long time
