Product Details

  • Vendor FORE Innovations
  • SKU 43-621
Description
  • Up to 800 rwhp (E85 capable)
  • Uses OE fuel rails
  • Regulator BEFORE OE 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.

  • Fuel Pump Module (dual pump)

This is a stand alone fuel system. Professional installation and a custom tune is required. Qualified installers must be able to interface to the OE harness and FPDM/FPCM, 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.
