* Perfect upgrade for aftermarket pumps, like Holley retrofit EFI modules, when more fuel is needed with turbos or nitrous * Can be used with carbureted or EFI applications * Inlet filter meets or exceeds original equipment specifications and provides improved filtration/durability * Filter, wiring pigtail, rubber hose, clamps, and rubber grommet included * Complete kit with all drop parts, accessories, and installation instructions * Compact enough to fit in existing hanger assemblies without modification Order the model recommended for your vehicle. Designed for applications requiring more fuel flow (utilizing the factory OE lines and mounting brackets), the 340 lph fuel pumps can also be used as a universal replacement-or upgrade for aftermarket applications requiring more fuel flow to support additional horsepower, while using power adders. The pumps can be regulated to support carbureted systems, as well, and all are compatible with gasoline or E85. Holley Sniper E85 in-tank electric fuel pumps are high-output models that fit the most popular EFI applications. Holley Sniper E85 In-Tank Electric Fuel Pumps Installation kits including a fuel strainer, fuel hose, harness pigtail, clamps, and wire connectors are sold separately. Some pumps require modifications to system wiring, fuel lines, and the fuel module, and should be professionally installed. This innovative design results in improved hot fuel flow, as well as minimal noise and current use, resulting in efficiency that's higher than conventional pumps. The blades feed two high-pressure pumping channels, as opposed to a conventional single-stage pump that uses an impeller with a single row of blades at its outer edge. Some high-performance models, including those designed for engines with more than 750 hp, feature a dual-channel turbine design for maximum efficiency in high-pressure and high-temperature applications. Most Walbro in-tank fuel pumps utilize a proven gerotor design. All pumping components have been validated to OEM specifications for use in E85/flex fuel applications. The outside dimensions, however, of many pumps are compact enough to fit existing hanger assemblies, without modification.

Walbro electric in-tank fuel pumps are available in a variety of flow ratings, including pumps that flow significantly more fuel at higher pressure. * No return line needed (all return fuel is handled inside the tank)

* Fuel pressure is regulated internally and preset at 58 psi, eliminating the added expense of purchasing an external fuel pressure regulator * Holley includes a HydraMat with its unique internal reservoir to keep fuel available at the pick-up, while also providing protection from contaminates

* Module includes a pre-calibrated fuel-level sending unit that is designed to work with the factory fuel gauge already in vehicle Order the model designed for your vehicle application.Īdditional features of Holley OEM-style EFI fuel tank modules: There's no need for modifications-and you won't have to replace your 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 some EFI-rated fuel hose and hose clamps. Holley OEM-style EFI fuel tank modules are designed as a direct replacement for your factory pick-up and sending unit.
