The HFP-439B 43mm is a direct replacement intank fuel pump for EFI BMW motorcycle applications. This is a direct fit pump, that requires no wiring modifications, and contains the correct OEM sized strainer which is not offered by other sellers, and is essential to do the job correctly. Cleaning and reusing your OEM strainer will lead to premature failure, as strainers become varnished internally, which makes the pump work harder.
QFS replacement fuel pumps, modules, and assemblies are designed to meet or exceed OEM specifications, and feature upgrades that improve on the OEM design. Upgraded polymers, brushes, and commutators ensure long life and durability in multiple fuel blends. Each QFS fuel pump is backed by a lifetime free replacement warranty. If there is any issue of any kind at any time, give us a call or email us and we will replace the pump free of charge.
