Converts the factory returnless fuel system into a traditional return-style setup by adding a second pump (a 525 lph main and 320 lph secondary, both E85-safe) plus a boost-referenced regulator and gauge, while reusing the stock fuel rails with an adapter.
why this one — It adds real return-style fuel capacity (rated for 500-750 hp) on early Coyote F-150s without replacing the factory rails, at a lower price than a full billet-rail system.
Fuel delivery support hardware; raises fuel headroom for other power mods but carries no standalone horsepower or torque claim.
