Fore Innovations Level 3 Dual Pump Fuel System (51-523) - 2006-2010 Jeep Grand Cherokee SRT8 WK1
The Fore Innovations Level 3 Dual Pump Fuel System is a boost-referenced return-style fuel system designed to support 1,200+ RWHP in the 2006-2010 Jeep Grand Cherokee SRT8 WK1. This Level 3 configuration positions the F4i Fuel Pressure Regulator before the fuel rails, with the feed lines entering the fuel rails and the opposite ends of the rails plugged.
Included Components
- Grand Cherokee SRT8 WK1 dual fuel pump module
- F4i Fuel Pressure Regulator
- 88mm inline fuel filter
- Billet Hemi Fuel Rails
- 30 feet of fuel line with choice of available fuel line type
- 10 matching hose ends
- 6 billet low-profile 90-degree fittings
- 4 straight AN-to-O-ring fittings
- 3 -8 O-ring plugs
- 10 hose straps with stainless hardware
- 2 1/8 NPT plugs
- Fittings, hose, and hardware required for typical fuel line plumbing
E85 Compatibility
This system can be used with E85 when equipped with the optional stainless filter element and E85-rated fuel pumps. Fore specifies the AEM 50-1200 or TI Automotive F90000267 fuel pumps for E85 use with this system.
Fuel Pump Controller
Fore recommends the FC2 controller for dual GSS342 or larger pumps in track-only applications. The FC3 is recommended for larger pumps to help reduce fuel heating. Contact us for assistance when selecting the appropriate controller for your application.
Fuel Pickup and Tank Level
The Fore Innovations fuel pump module does not use a basket surrounding the pumps because the basket can become a restriction at lower fuel levels. Basket size is limited by the fuel tank access opening and tank depth, which can be insufficient for vehicles capable of consuming large amounts of fuel for more than 10-12 seconds.
Due to the limitations of the Grand Cherokee's large single-sump fuel tank, Fore recommends treating 1/4 tank as empty when using this module.
Fuel Smell and Pump Noise
Fore uses hermetic wire seals to provide a complete seal at the wire pass-through, sealing both the inside and outside of each individual conductor. When PTFE fuel hose is selected, fuel smells should be virtually eliminated while the vehicle is sitting or running.
The in-tank Fore module is substantially quieter than an external fuel pump, but pump noise varies depending on pump size and quantity. Larger pumps are louder than smaller pumps, and two pumps will produce more noise than a single pump. A single turbine-style pump will generally be inaudible in a typical vehicle with an upgraded exhaust system. For customers sensitive to pump noise, Fore recommends a dissimilar pump setup using the smallest suitable pump as the primary.

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.
