Product Details

✓Fitment & SKU: Fits Harley-Davidson Softail models (Heritage, Fat Boy, Deluxe, Springer, Night Train, Standard, Screamin' Eagle) from 2001-2007. SKU: HFP-PR440.
✓This precision-calibrated fuel pressure regulator (400KPA / 58 psi) is designed to maintain the exact rail pressure required for Harley's Efi system, ensuring optimal fuel atomization and consistent engine performance
✓Manufactured with high-quality, ethanol-resistant housing and internal diaphragms, this regulator is built to withstand the chemical stresses of modern pump gas and provide a long service life in high-heat V-Twin environments
✓When should you replace your regulator? If your bike is experiencing hard starting, mid-range hesitation, or running "rich" or "lean" codes, the internal spring or diaphragm has likely failed; restore factory-spec fuel flow to protect your engine and improve throttle response
