Fore Innovations 2018+ Ford Mustang GT/Bullit/Mach 1/Dark Horse 5.0L L1 Dual Pump Return-Style Fuel System - 800rwhp on gas

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. Fore Innovations will not provide assistance with ECU integration/tuning or elimination of alarm codes or the CEL.

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.

Fuel Pressure Settings:
1. Fuel pressure with static fuel pressure regulation must be set to [43 psi + maximum boost] or 54 psi (whichever is greater).
2. Fuel pressure with manifold referenced fuel pressure regulation must be set to 54psi with a Primary fuel pump activated. (boost signal after throttle body)
3. Fuel pressure with boost referenced fuel pressure regulation should be set to 54 psi with vacuum off. (boost signal before throttle body)
4. Use L1E or L2 fuel system to operate outside these parameters.

Frequent Asked Questions

Q: Can I use this system with E85?
A: Yes, as long as you select microglass ssd or stainless filter element and select E85 rated fuel pumps.

Q: What do I need to add a Flex-Fuel sensor to this system?
A: Fore offers flex-fuel intercept fittings that uses a GM/Continental style flex-fuel sensor which is good for those making 1100 HP if you're making over 1100 HP we recommend the AFD E-Sense Billet Sensor which can have fittings up to -12 AN which is capable of handling 2000+ HP.

Q: Should I select the FC2 or FC3 controller?
A: FC2: controller can only operate two pumps simultaneously, using OE or aftermarket switching signal. Best for controlling two small fuel pumps for street duty, or two large fuel pumps for track use only.

FC3: controller can run 1, 2, or 3 pumps full time, with remaining pumps activated on demand. Requires external switch (i.e. Hobbs, RPM, etc) best for controlling two or three large fuel pumps for street duty and minimizing heat.

Q: Should I select the F2i fuel regulator or F4i regulator?
A: F2i: The standard option included in most kits. Features 2 ORB-8 pressure ports, 1 1/8" NPT auxiliary port, 2 1/8" NPT map reference ports, and 1 ORB-8 return port. Ideal for most builds not running additional or DI fuel rails. Note: additional fittings or blocks may be needed in tight routing situations.

F4i: The best option when running fuel rails and DI rails simultaneously into a single regulator, 16-injector dual fuel rail setups, or supplying fuel to a nitrous system. Features 2 ORB-8 + 2 ORB-10 pressure ports, 2 1/8" NPT map reference ports, and 1 ORB-10 return port. Note: Some installations are simplified when using the F4i regulator as having the 4 pressure ports can eliminate use of extra fittings or blocks making for a cleaner less expensive fittings combo.

Q: What is the difference between PTFE and RH235 Fuel Hose?
A: PTFE Hose: Lasts indefinitely with all fuel types and is non-permeable (no fuel odor in enclosed spaces). Downsides are longer installation times, stainless steel outer braid can scratch surfaces and make noise/vibrations.

Red Horse 235 Hose (RH235): Features nylon outer sleeve protects surfaces and reduces noise/vibration and they're faster to assemble. Downsides are they only have a 5–7 year service life and requires a cable cutter to cut.
