Restore consistent fuel pressure and eliminate seized check valves on your Harley Davidson EFI models with this dedicated MC400 and MC300 fuel system rebuild kit. Engineered for factory 2001 through 2026 motorcycle platforms, the set houses precision-engineered wrenches and extraction instruments that allow independent technicians to disassemble, clean, or replace leaking inlet components directly at the pump housing. By addressing restrictive flow and pressure loss at the source, you can prevent hard starting, rough idling, and sudden power drops without relying on expensive dealership service bays.

Benefits & Maintenance Tips Clear carbon buildup from the brass guide passages using isopropyl alcohol before reassembly to guarantee smooth plunger movement. Lubricate every rubber O-ring with fresh SAE 20W-30 motor oil to prevent pinching and ensure an immediate pressure hold upon first ignition. Keep the driver sockets grouped near your workbench to avoid cross-threading hardened fasteners during bench preparation. Product Specifications
