F4 Adjustable Fuel Pressure Regulator - by Fore Precision Works

Fore's F4 adjustable FPR gives you all of the features of the F2 regulator but it has four inlet ports(dual -10 AN and Dual -8 AN) and a -10 AN return port. All of those connections makes the F4 capable of regulating the pressure of even the most ambitious racing fuel system. The stainless valve seat increases stability and extends the regulators life(hence the 3 year warranty). Just like the F2 the F4 has a Flourocarbon / Nomex diaphragm, a 1/8" NPT fuel pressure gauge port, a 1:1 boost pressure reference(unlike a rising rate regulator), and includes a mounting bracket. Other features include chatter free operation and full adjustably from 25 to 70 PSI. Its fully compatable with HEMI 5.7L or 6.1L (or other setups with -8 AN lines) fuel systems for up to 2,000 horsepower and my be used with any fuel blends. Fore makes a high quality, yet cost effective FPR for the new Challenger, Dodge Charger, Magnum, Chrysler 300c, and other performance cars.
