Holley Street Performance mechanical fuel pumps are designed to work with stock or mildly modified engines. Ranging in performance styles of 80 to 225 gph, their body castings can be rotated 360 degrees to ease mounting in difficult places and they have large orifices for high flow rates. These pumps are not compatible with methanol or alcohol fuels and should not be used with fuel injection systems. A fuel pressure regulator is required for 130 gph versions.

Holley Sniper E85 in-tank electric fuel pumps are high-output models that fit the most popular EFI applications. The pumps can be regulated to support carbureted systems, as well, and all are compatible with gasoline or E85. 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. Order the model recommended for your vehicle. Features include: * 340 lph E85-compatible * Designed for in-tank use only * Compact enough to fit in existing hanger assemblies without modification * Complete kit with all drop parts, accessories, and installation instructions * Filter, wiring pigtail, rubber hose, clamps, and rubber grommet included * Inlet filter meets or exceeds original equipment specifications and provides improved filtration/durability * Can be used with carbureted or EFI applications * Perfect upgrade for aftermarket pumps, like Holley retrofit EFI modules, when more fuel is needed with turbos or nitrous

Holley EFI Hi-Flow billet fuel rails offer flow capacity for high horsepower applications and billet aluminum construction that is machined and black anodized for great style under the hood. Laser-etched with the "Holley EFI" logo, the fuel rails feature a 5/8 in. diameter fuel passage, -8 ORB ports on each end, and an 1/8 in. NPT port for a fuel gauge installation if you choose to do so. Holley EFI Hi-Flow billet fuel rails are designed with the factory injector clip reliefs so that your factory injectors and retaining clips can be reused.
