Fuelab 49469 494 Series In-Tank Fuel Pump 340LPH E85 80mm Inline Inlet GM Apps

Compatible Applications

• Universal - designed to fit most GM in-tank hanger assemblies and sending units using an 80mm body and inline inlet/outlet orientation
• Compatible with most popular EFI and carbureted applications using 19mm inlet and 5/16 in (9mm) outlet connections
• E85, gasoline, and flex-fuel compatible
• Note: The 49469 uses an inlet inline with the outlet (GM applications) - for applications requiring an offset inlet, see Fuelab 49442

Fitment Notes

• In-tank use only - not designed for external inline installation
• 80mm body length is designed for OE fitment in GM hanger assemblies - verify hanger assembly dimensions and inlet/outlet orientation before ordering
• Sending unit not included - this is the pump module only
• 19mm inlet / 9mm (5/16 in) outlet - confirm these port sizes are compatible with your hanger assembly and fuel lines before ordering
• Confirm fuel type compatibility (gasoline, E85, or flex-fuel) with your existing fuel system components before installation
• Professional installation recommended - fuel system work requires relieving fuel pressure, working in a well-ventilated area, and following all safety precautions

Features

• 340 LPH flow rate at 3 bar / 13.5V (90 GPH at 45 PSI) provides high-output fuel delivery for modified and high-horsepower EFI builds that exceed the capacity of OEM or standard-output replacement pumps
• E85 and gasoline compatible - supports flex-fuel and dedicated E85 builds without requiring a separate pump or fuel system conversion
• Internal check valve holds fuel rail pressure after engine shutdown, shortening re-prime time on restart, reducing hot-start issues, and minimizing evaporative emissions
• 80mm body length matches GM OEM pump dimensions for direct-fit installation in most GM in-tank hanger assemblies - no custom fabrication or adapter required
• Inlet inline with outlet orientation specifically designed for GM applications - matches the port geometry of GM OEM hangers
• Each pump is individually tested and serialized - a flow and current draw report specific to that unit is included in the box, confirming it meets rated performance before installation
• Compatible with both carbureted and EFI applications for broad versatility across performance and restoration builds
• Compact and lightweight design fits most existing hanger assemblies without modification
• Backed by Fuelab's Limited Lifetime Warranty

Product Description

The Fuelab 49469 is the 494 Series High Output In-Tank Electric Fuel Pump in the GM application configuration - 340 LPH at 3 bar, E85 compatible, with the inlet inline with the outlet to match GM OEM hanger assembly geometry. The 80mm body length is sized for direct-fit installation in most GM hanger assemblies without modification, making the 49469 the straightforward upgrade path for GM-based performance builds that have outgrown the factory pump or a standard-output replacement.

At 340 LPH (90 GPH at 45 PSI), the 49469 delivers meaningfully more fuel than stock pumps on most GM platforms, supporting modified engines running larger injectors, boost, or E85. The E85 compatibility is built in - no separate pump required for flex-fuel or dedicated E85 setups. The internal check valve holds fuel rail pressure after shutdown, reducing hot-start issues and cutting evaporative emissions. Every 49469 is individually tested and serialized, with a specific flow and current draw report included in the box - a level of quality documentation uncommon at this price point. The kit includes a rubber sleeve, end cap, pre-filter, hose, clamps, and wire leads for a complete installation. Sending unit not included. For non-GM hanger assemblies with offset inlet orientation, see Fuelab 49442. Backed by Fuelab's Limited Lifetime Warranty.
