For 91-93 octane, you don't need a FRL for 12PSI or 430HPish. E85 uses more fuel, so fuel return may be needed.My build will be around 400-450 whp, can i run the fpr without a return line?
Hey what’s up is this Korey from the YouTube channel Korey Wright with the black 2dr Civic Si?I’m gonna be boosting my 9th gen and i have a ACUITY fuel rail with an acuity fuel pressure gauge. I bought an AEM Fuel Pressure Regulator for the build. Where would i mount the FPR and how should i run the fuel lines for everything to work properly?
