Fuel Pressure Regulators & Adjustable FPRs
Fuel pressure regulators maintain consistent fuel pressure at the injectors regardless of engine load, vacuum changes, and boost levels. An adjustable fuel pressure regulator is essential for tuning fuel delivery on modified engines, forced-induction builds, and any vehicle running larger injectors, higher-flow fuel pumps, or alternative fuels like E85 that require different base fuel pressures.
OneFastShop carries fuel pressure regulators including adjustable 1:1 boost-referenced regulators, OE-replacement regulators, bypass-style regulators, dead-head regulators, dual-port and triple-port regulators, regulator gauge kits, and direct-fit and universal applications for performance fuel systems.
Every fuel pressure regulator at OneFastShop ships brand-new with manufacturer warranty coverage. Whether you're setting base pressure on a fresh fuel system build, adding an adjustable FPR for E85 tuning, or replacing a failed factory regulator, OneFastShop has the right FPR.
