Mustang Return Style Fuel System
SKU: 8704FS.MD.2
Moderate — 2–4 hours
Description
The system utilizes a billet 6061 aluminum fuel hat with a two-piece design that consolidates fuel pumps to a single port, eliminating the need for welding and extra fittings. It includes O-ring fittings for easy installation and a reliable seal, anodized black for E85 compatibility and corrosion resistance. The kit comes with a 10AN supply line, an in-line fuel filter, a Y-block for fuel rails, and a 1:1 boost-referenced fuel pressure regulator. An 8AN return line kit is also included but can be deleted for return-less systems.
