Harley-Davidson Fuel Pump with Regulator vs FPF FPA-1021 Fuel Pump Assembly for Harley Davidson 01-05 Softail

Both are FPF-built drop-in fuel pump kits for EFI Softails, so the real split is fitment and completeness. Product A covers 2001-2007 Softails and adds a fuel filter, but its tank seal gasket draws complaints about leaking and it omits the plastic regulator housing. Product B is a full assembly with sending unit and strainer for 2001-2005 Softails only, and its 4.7 rating from 49 owners backs the fit. Buy B for a 2001-2005 bike; buy A only if you have a 2006-2007 or need the filter included.

• Choose the HFP-370HD-RT5F if you ride a 2006-2007 Softail, or a 2001-2005 model and want a fuel filter in the kit.
• Choose the FPA-1021 if you have a 2001-2005 Softail with the black harness and want a complete assembly with sending unit and strainer.
