I have the SiR h23a vtec motor from the accord. my Fuel pressure regulator is bad, and i need to replace it. I just ordered one for the 2001 h22 but it is not the right one. and will not bolt up. What fpr do I need to use? If I can't find one can i just buy an adjustable one or will I still have to get fuel rail because fpr wont mount?

 

the f23 vtec fuel pressure regulator has same mounting, but the hoses are bent differently. Someone please help

 

I would suggest after market if you can't find anything. All they sell is an adapter plate that goes where your current FPR sits and that adapter plate connects to a hose that goes to your aftermarket FPR where ever you want to put it. Than you connect the return line to where the origional return line is going. If you go this route varify the proper pressure for your motor. I believe its around 30 either way, but with vacuum and without, its two different pressures (manifold vac hose hooked up)
