Fuel Pump Center Inlet Gas In-Tank

Technical Specifications:

• Brand: Walbro / TI Automotive
• Part Number (MPN): GSS342G3-3
• Product Type: High Pressure In-Tank Fuel 
• Flow Rate: 255 LPH (Liters Per Hour)Pump
• Inlet Configuration: 22mm Center Inlet (Inline with outlet)
• Outlet Configuration: 8mm (5/16") Hose Barb
• Operating Pressure: Designed to support 25-70 PSI systems.

Performance & Fitment Features:

• Proven Gerotor Design: The industry standard for naturally aspirated and forced-induction EFI applications supporting up to 500 horsepower.
• CRITICAL FUEL WARNING: STRICTLY GASOLINE ONLY. This pump is designed exclusively for standard unleaded and race gasoline. It is NOT compatible with E85, Methanol, or high-percentage Ethanol blends. Running alcohol-based fuels will strip the internal lubrication, seize the pump, and immediately void the manufacturer's warranty. (For E85 applications, refer to the F9000 series pumps).
• Installation Protocol (Submersible Hose): This is an in-tank pump. You MUST use submersible-rated fuel hose (SAE 30R10 specification or PTFE) to connect the pump outlet to your fuel hanger. Standard EFI hose (SAE 30R9) will dissolve when submerged in gasoline, leading to catastrophic engine failure and clogged injectors.
• Electrical Demand: High-flow pumps draw significantly more amperage than factory pumps. To prevent voltage drops or melting your factory harness, a dedicated heavy-duty relay and upgraded wiring kit are strictly required.

Federal Emissions Compliance:

• Emissions Code: 5 (Replacement Part)
• Status: This is an internal fuel delivery component that does not directly alter factory emissions control equipment. It is strictly legal for sale, installation, and street use in all 50 US states, including California. No CARB Executive Order (EO) is required.

Disclaimer & Warranty Information: Onyx Customs FL acts exclusively as an authorized retailer of high-performance automotive components. We do not manufacture this product. Modifying pressurized in-tank fuel systems carries extreme risk. Improper installation, utilizing non-submersible hoses, running incompatible fuels (E85), or failing to wire a proper relay will result in severe electrical fires, engine detonation from fuel starvation, or total vehicle loss. Onyx Customs FL assumes no liability for direct or indirect damages, engine rebuilds, or diagnostics costs resulting from the incorrect installation or misuse of this component. All manufacturing defects and warranty claims are strictly the responsibility of, and must be directed to, TI Automotive. We strictly mandate that all fuel system components be installed and calibrated by a certified professional race mechanic.
