Sniper EFI Fuel Pump Module 340 LPH Drop-In

The Holley Sniper EFI Fuel Pump Module 340 LPH Drop-In is a high-flow electric fuel pump engineered for modern EFI-equipped engines requiring robust fuel delivery under sustained load. This in-tank pump assembly delivers 340 liters per hour—sufficient capacity for naturally aspirated and moderately boosted applications—and integrates seamlessly into existing fuel tank configurations as a complete drop-in replacement. The module is configured with industry-standard 6 AN inlet and outlet ports, ensuring compatibility with common aftermarket fuel system components and plumbing standards.

The 340 LPH flow rating represents the upper range for naturally aspirated engines and serves as a practical baseline for forced-induction builds running moderate boost levels. Proper fuel delivery depends not only on volume but also on maintaining consistent pressure and accounting for fuel return line dynamics; the Sniper module's engineering supports the full operating envelope of modern Holley EFI systems. The black finish resists corrosion in standard in-tank environments, and the modular design allows technicians to service or replace the pump assembly without extensive fuel system disassembly. Weight of 4.61 lbs reflects the robust construction and internal fuel filter integration typical of performance-grade pump modules.

This pump is specified for builders and tuners transitioning to Holley Sniper EFI systems or upgrading fuel delivery capacity on existing installations. It suits street, strip, and road-race applications where consistent fuel supply is non-negotiable. Buyers integrating this module should verify tank compatibility and confirm that existing fuel lines or adapters match the 6 AN port configuration; aftermarket fuel system builders often stock matching fittings and hose assemblies. The drop-in design minimizes installation complexity for users with basic mechanical skill and proper tools.

Holley's Sniper EFI line positions the 340 LPH pump in the mid-to-high tier of in-tank module capacity, balancing flow sufficiency against electric current draw and fuel cooler efficiency. Users running carbureted or older mechanical fuel injection systems may find lower-capacity pumps adequate; the 340 LPH rating assumes integration with Sniper's closed-loop ECU management and standard return-line architecture. Verify your specific engine displacement, boost level, and fuel system layout before purchase to ensure this pump meets duty cycle requirements.
