The Jones Racing Products Fuel Regulator w/ Bypass Billet w/ Idle Jet (model FP-8009-R2) is a precision fuel delivery component engineered for high-performance racing, street applications, and alternative fuel systems. This inline regulator maintains consistent fuel pressure across a range of 4.5 to 9 psi, making it suitable for carbureted engines, EFI conversions, and fuel injection tuning where stable supply pressure directly affects engine response, idle quality, and overall drivability. Built to handle gasoline, E85 ethanol blends, and methanol, this regulator serves racers, hot rodders, and tuners who demand reliable pressure control in demanding operating conditions.
Constructed from aluminum with black anodized finish, the FP-8009-R2 features a billet housing that provides durability and heat dissipation in engine bay environments. The regulator incorporates a bypass function—a critical design element that routes excess fuel back to the tank, protecting fuel pumps and injection systems from overpressure while allowing the idle jet port to fine-tune low-rpm fuel delivery characteristics. Threaded connections include 3/8-inch NPT inlets, outlet, and bypass ports, plus a 1/8-inch NPT port for boost reference or gauge installation, enabling precise integration into both naturally aspirated and forced-induction fuel systems. Weighing just 0.59 pounds, it mounts compactly in engine compartments with minimal footprint.
Ideal for racers, vintage car restorers, and performance tuners upgrading fuel system architecture, this regulator pairs seamlessly with aftermarket fuel pumps, carburetors, and EFI kits requiring stable supply pressure. Installation requires NPT-compatible fuel line adapters and mounting bracket fabrication; the bypass loop prevents system damage from pressure spikes during transient throttle conditions. Technicians routinely specify this model for Le Mans-style fuel cells, methanol racing programs, and street/strip vehicles where fuel delivery precision directly influences horsepower consistency and engine longevity.
