FFG Return Style Fuel Line System
Pump to rail. Rail to regulator. Regulator back to tank. A return system is the old answer and it is still the right one. Fuel circulates; the regulator sets the pressure and the surplus goes home to the tank. Nothing sits still and heats up; nothing spikes when you lift. It matters most where pressure is hardest to hold. Put boost behind an engine and a returnless setup has to react; a return system simply maintains. Under a turbo or a blower that difference shows up as a rail that does not sag when you need it. The kit is complete: 25 ft of AN-06 braided soft line; an Aeromotive EFI regulator preset at 55-58 PSI; an Aeromotive liquid filled fuel pressure gauge; a serviceable EFI in-line filter; AN-06 fittings straight; 90 degree swivel and quick connect; O-ring fittings for the tank and regulator and rubber insulated loom clamps for the frame rail. Those loom clamps are the detail you appreciate three years in. Zip ties will hold long enough to fire the truck up. They will not survive the miles ahead. Building a Coyote swap on a returnless fuel rail? The FFG returnless kit is the other half of this conversation.
