Holley Sniper EFI Fuel Tank Modules are designed as a direct replacement for your factory pick-up and sending unit. There is no need to purchase a custom EFI fuel tank. You can even retain the factory fuel hard line, just connect the outlet of the pump module to the hard line on your vehicle with EFI-rated fuel hose and hose clamps available in the Earls Vapor Guard line. The fuel pump is rated at 350 LPH, capable of supporting 750 EFI horsepower. It's internally regulated at 58 psi, so you don't need an external regulator or return line - this module returns the fuel right inside the tank! It's filtered by Holley's HydraMat, an amazing patent-pending fuel reservoir system that reduces fuel starvation issues that might otherwise occur while cornering, accelerating, stopping, traversing inclines, and during low fuel conditions. The integrated fuel level sending unit is pre-calibrated to work with your factory fuel guage.
