Fore Innovations – GM Zeta / Sigma II L1 Fuel System (Dual Pump)

$1,316.00

-

800 rwhp capable return fuel system uses the factory fuel rails. The upgraded feed fuel is regulated before entering the factory fuel rails. Proper upgraded feed line and filtration included. Perfect system for applications where factory fuel rails must be used.

Fuel system becomes E85 capable by choosing F90000267, F90000274, F90000285 fuel pumps AND microglass SSD or stainless filtration. We generally prefer the L2 or L4 systems over the L1 (or L3) configuration since the engine must be able to start on fuel vapor. Engine start with E85 may be challenging and will require additional consideration from the tuner.

**PLEASE CAREFULLY SELECT FUEL PUMPS BASED ON YOUR FUEL TYPE THAT YOU WILL BE RUNNING. SEE FUEL PUMP SELECTION DESCRIPTIONS BELOW. BUILT TO ORDER ONLY / NO RETURNS OR REFUNDS ON FUEL SYSTEMS, FUEL SYSTEM COMPONENTS, FUEL PUMPS OR ELECTRICAL COMPONENTS.

Fuels * 

Please select the fuel(s) that you intend to run with this fuel system.

Gasoline / race gas: choose if you are will only be running typical pump gas or race gasoline, such as MS109, C16, Q16, etc.

Ethanol blends, gasoline, race gas: choose if you will be running a combination of gasoline, race gas, E85, E98, E85R, C85, etc.

Methanol is not currently supported or recommended with our fuel systems.

LS Intake * 

If you selected “OTHER” please enter the correct intake below

Primary Fuel Pump * 

You MUST make a primary fuel pump selection.

Walbro GSS342 G3
255lph best for gasoline-only cars when the secondary pump(s) are large enough to supply fuel for maximum load.

Walbro GSS352 G3
350lph gasoline-only pump, same physical size as GSS342 G3.

TI Automotive F90000262
400lph gasoline-only pump when more capacity than GSS342 G3 is required.

TI Automotive F90000267
430lph E85 rated. Recommended when maximum fuel pressure will not exceed 75 psi. Do not use with 274 secondary pump.

TI Automotive F90000274
430lph E85 rated. Recommended when maximum fuel pressure may exceed 75 psi (intermittently) Do not use with 267 secondary pump.

TI Automotive F90000285
470lph E85 rated. 10% more flow and 25% more heat than F90000274. Recommend 274 for primary use over this pump unless the extra capacity is required.

TI Automotive F90000295
535lph E85 rated. Race use only, no internal check valve. (entire fuel system loses pressure if primary 295 fails)

TI Automotive F90000295 + FCV
Same as F90000295 plus adds a check-valve on the inlet of the filter for certain applications. (entire fuel system loses pressure if primary 295 fails)

Secondary Fuel Pump * 

You MUST make a secondary fuel pump selection.

Walbro GSS342 G3
255lph small diameter pump for gasoline-only applications.

Walbro GSS352 G3
350lph small diameter pump for gasoline-only applications.

TI Automotive F90000267
430lph E85 rated. Recommended when maximum fuel pressure will not exceed 75 psi.

TI Automotive F90000274
430lph E85 rated. Recommended when maximum fuel pressure may exceed 75 psi (intermittently) Do not use with 267 primary pump.

TI Automotive F90000285
470lph E85 rated. 10% more flow and 25% more heat than F90000274.

Electrical Upgrade * 

Fuel Lines * 

PTFE (PTFE core with stainless steel outer reinforcement)

ADVANTAGES
Compatible with all automotive fuels, lubricants, and coolant
Infinite shelf and service life
Non-permeable = no smell when vehicle parked in enclosed locations
Small outer diameter for AN size = small bend radius, light weight
Expect to last lifetime

DISADVANTAGES
May contribute to NVH (Noise, Vibration, Harshness)
Stainless braid may damage contacted surfaces
Expect longer installation times

FlexLP (stainless reinforced polymer core with nylon outer braid)

ADVANTAGES
Compatible with all automotive fuels, lubricants, and coolant
Low permeable = no smell when vehicle parked in enclosed locations
Fast to assemble and install
Will not contribute to NVH (noise vibration, harshness)
Soft outer braid will not damage contacted surfaces

DISADVANTAGES
Expect 5-7 year life
Requires cable cutter to cut

Filtration Media * 

CELLULOSE
Use with gasoline/race gas ONLY. 10 micron nominal, 14 micron absolute filtration. Disposable. Recommend annual replacement.

MICROGLASS SSD
Use with all fuel types and blends (gasoline, race gas, E85, E100, M5, diesel). Provides 12 micron absolute filtration. Disposable. May require frequent servicing in alcohol and alcohol blended fuels. Recommend filter loss monitoring with alcohol blends to determine replacement interval.

STAINLESS STEEL
Use with all fuel types and blends (gasoline, race gas, E85, E100, M5, diesel). Provides 10 micron nominal, 26 micron absolute filtration. Re-usable. Recommend annual backwash.

This is a stand alone fuel system. Professional installation and a custom tune is required. Qualified installers 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.
