  • 2011-2017 Mustang GT or V6 with factory fuel rails

800 rwhp capable return fuel system uses the factory fuel rails. The upgraded feed fuel is regulated before entering the factory fuel rails. Proper upgraded feed line and filtration included. Perfect system for applications where factory fuel rails must be used.

Fuel system becomes E85 capable by choosing F90000267, F90000274, F90000285 fuel pumps AND microglass SSD or stainless filtration. We generally prefer the L2 or L4 systems over the L1 (or L3) configuration since the engine must be able to start on fuel vapor. Engine start with E85 may be challenging and will require additional consideration from the tuner.

INCLUDES
  • S197C Fuel Pump Module (dual pump)
  • F1i Fuel Pressure Regulator
  • 88mm Inline Fuel Filter
  • FCV Checkvalve
  • All fittings, hose, and hardware necessary to complete typical fuel line plumbing
-25 feet fuel line (your choice)
-Qty 8 compression style billet hose ends
-Qty 4, low profile 90 degree billet o-ring fittings
-Qty 3, straight AN to o-ring fittings
-Qty 8, hose straps with stainless mounting screws
-Qty 1, 3/8 EFI (female) to AN-8 (male) adapter

This is a stand alone fuel system. Professional installation and a custom tune is required. Qualified installers and tuners must be able to interface to the OE harness and FPDM, understand proper component placement, hose routing, and deliver the vehicle with factory-like pump prime/on/off logic with no error codes. Fore Innovations will supply basic system schematics and detailed component level instructions, and can provide troubleshooting of the performance and function of our system and components.

This fuel system generates substantially more heat and capacity than the original fuel system. The high powered fuel pumps make much more heat than the factory pump and the composite fuel tank construction acts as an insulator and stores heat. Additionally, the shape of the factory fuel tank limits the pickup capacity of this fuel system. The user (driver) must keep more fuel (than normal) in the tank at all times to minimize heat damage and ensure adequate fuel pickup.
