Fore Innovations SN95 4V Level 4 Triple Pump Fuel System (55-634) - Mustang Cobra & Mach 1

The Fore Innovations SN95 4V Level 4 Fuel System is a return-style fuel system capable of supporting up to 1,800 RWHP for select Mustang SVT Cobra and Mach 1 applications. Using Fore's legacy hose routing, the feed line is split through a compact billet Y-block to supply both billet fuel rails, with each rail then connected to the F2i Fuel Pressure Regulator.

This Level 4 configuration routes the fuel rails in parallel with the F2i Fuel Pressure Regulator mounted after the rails. Combined with Fore's triple pump module, 88mm inline filter, billet Y-block, and SN95 4V billet fuel rails, the system provides the fuel capacity needed for serious high-horsepower applications.

Included Components

  • SN95 triple fuel pump module
  • 88mm inline fuel filter
  • Compact billet 2-1 O-ring Y-block
  • F2i Fuel Pressure Regulator
  • SN95 4V billet fuel rails
  • 35 feet of fuel line with 14 matching hose ends
  • 8 straight AN-to-O-ring fittings
  • 6 low-profile 90-degree AN-to-O-ring fittings
  • 2 0.6-inch O-ring extensions
  • 12 hose straps with stainless mounting screws
  • 2 1/8 NPT plugs
  • Fittings, hose, and hardware necessary for typical fuel line plumbing

Installation & Tuning Requirements

This is a standalone fuel system. Professional installation and a custom tune are required. The qualified installer and tuner must be able to interface the system with the OE wiring harness and FPDM, understand proper component placement and hose routing, and configure factory-like fuel pump prime and on/off operation without generating error codes.

Fore Innovations supplies basic system schematics and detailed component-level instructions and can provide troubleshooting assistance for the performance and function of its fuel system and components. Tuning and interfacing with the OE wiring harness, ECU, or FPDM(s) are the responsibility of the installer and tuner.

Fuel Heat & Fuel Level

This system generates substantially more fuel capacity and heat than the original fuel system. High-performance fuel pumps generate more heat than the factory pump. The shape of the factory fuel tank also limits the fuel pickup capacity of the system.

The driver must maintain a higher-than-normal fuel level in the tank to help minimize heat-related damage and ensure adequate fuel pickup.

Available Options and Upgrades

Electrical Options

  • None: Base module configuration with approximately 6"" of fuel pump power wire extending from the hermetic seal.
  • FC2 Controller with 6-Gauge Wiring: Operates both pumps simultaneously using factory control. Best for two smaller street-duty pumps or two large pumps in track applications where increased fuel heat is less of a concern. Can control secondary pumps on a triple-pump module when a small primary pump is powered by the OEM harness. Includes 14' of 6 AWG power wire, 100-amp fuse, 3' ground wire, 7' 12 AWG pump leads, and sealed Delphi connector.
  • FC3 Staged Controller with 4-Gauge Wiring: Independently controls the secondary pump(s) from the primary pump using factory control plus a secondary trigger. Recommended for two or three large pumps in street applications to help minimize fuel heat. Includes 14' of 4 AWG power wire, 100-amp fuse, 3' ground wire, 7' 12 AWG pump leads, and sealed Delphi connector.
  • Delphi Connector / Pigtail Only: Includes a sealed Delphi connector and 7' of 12 AWG pump leads. Installer is responsible for supplying and properly configuring the required fuses and relays.

Filtration Media

  • Cellulose: 10-micron nominal / 14-micron absolute disposable element with aluminum endcaps and Viton O-ring. For gasoline and race gas. Recommended for Injector Dynamics injectors.
  • Microglass SSD Anti-Static: 12-micron absolute disposable, static-dissipating element with aluminum endcaps and Viton O-ring. Compatible with gasoline, race gas, E85, E100, M5, diesel, and other fuel blends. Recommended for Injector Dynamics injectors.
  • Stainless: 10-micron nominal / 26-micron absolute reusable stainless element with stainless endcaps and Viton O-ring. Compatible with gasoline, race gas, E85, E100, M5, diesel, and other fuel blends.

Fuel Filter Upgrades

  • 128mm Filter: Upgrades the standard 88mm filter to a larger 128mm filter for increased filtration capacity and longer service intervals.
  • Billet Mounting Bracket: Provides a secure, show-quality underbody filter installation while keeping the filter accessible for maintenance.
  • Filter Monitoring Gauge and Fitting: Monitors fuel pressure before the filter to help identify restriction. Increasing pre-filter pressure can indicate a clogged filter, which can reduce pump performance, shorten pump life, and increase fuel temperature. Includes a fitting for proper gauge orientation.

Additional System Options

  • Honeywell Pressure Switch for FC3: 1/8"" NPT male pressure switch designed for installation in the intake manifold. Must receive both boost and vacuum signals.
  • Boost / Vacuum Manifold Kit: Includes Fore Innovations Boost / Vacuum Manifold, three 1/4"" barb fittings, and four plugs.
