Fore Innovations WK2 Hellcat Level 2 Triple Pump Fuel System (52-632)
The Fore Innovations WK2 Hellcat Level 2 Triple Pump Fuel System is a return-style fuel system capable of supporting 1,200+ RWHP with triple fuel pumps. Fore recommends operating one pump full time and activating the secondary pumps under load.
This Level 2 configuration routes the Billet Hellcat Hemi Fuel Rails in series with the boost-referenced F2i Fuel Pressure Regulator mounted after the rails. The in-tank supply system retains OE fuel transfer, fuel level sender, and EVAP functionality while adding upgraded feed and return lines, high-capacity filtration, and an FCV check valve.
E85 Applications
This fuel system can be configured for E85 by selecting F90000267, F90000274, or F90000285 fuel pumps along with microglass SSD or stainless filtration.
Included Components
- Cherokee WK2 triple fuel pump module
- F2i Fuel Pressure Regulator

- 40 feet of fuel line with choice of available fuel line type
- Matching hose ends
- 5 billet low-profile 90-degree O-ring fittings
- 4 straight AN-to-ORB fittings
- 2 tubular 180-degree hose ends
- 8 straight hose ends
- 1 -8 ORB plug
- 2 -8 ORB 1.25-inch port extensions

Hellcat OE Fuel Pressure Sensor Options
By default, this fuel system deletes the OE fuel pressure sensor. Fore offers additional fuel pressure sensor provisions that must be selected by the purchaser.
- Delete OE Fuel Pressure Sensor: Removes the factory fuel pressure sensor from the fuel system configuration.
- Inline Aftermarket Sensor: Includes a new AC Delco sensor and provisions for mounting it in a high-flow coupling, along with two additional hose ends. On this Level 2 system, the sensor can be installed without extending the OE electrical harness.
- Regulator Mounted Aftermarket Sensor: Includes a new AC Delco sensor and adapter for mounting the sensor directly to the fuel pressure regulator. The installer must extend the OE electrical harness to accommodate the new sensor location.
Installation Notes
Professional installation and a custom tune are required. This is a standalone fuel system. Qualified installers and tuners must be able to interface with the OE harness and FPDM, understand proper component placement and hose routing, and provide factory-like pump prime and on/off operation without error codes.
Fore Innovations provides basic system schematics, detailed component-level instructions, and troubleshooting assistance for the performance and function of its fuel system and components.
Fuel Level and Heat Considerations
This system generates substantially more fuel capacity and heat than the original fuel system. The high-output fuel pumps produce significantly more heat than the factory pump, while the composite fuel tank acts as an insulator and retains heat.
The shape of the factory fuel tank also limits the fuel pickup capacity of the system. More fuel than normal must be kept in the tank at all times 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.
