FITS FOLLOWING MODELS 2011+ Mustang GT 2015-2020 GT350 / GT350R 2013-2014 GT500 Use in conjunction with a complete return style fuel system for 1200+ rwhp with triple fuel pumps (recommended to run one pump full time, then activate secondary pump under load). Retains OE fuel level sender, EVAP functionality, and tank transfer, and filler neck. This component requires the use of external feed and return lines, external filtration (for injectors), external regulation, and an upgraded electrical system. Upgraded fuel rails and an inline check valve is recommended. Supplies port fuel injection and optional wet nitrous. See our complete fuel systems if the extra components are needed. E85 requires F90000267, F90000274 or F90000285 fuel pumps. This is part of 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/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.
