EFI Or Carbureted

Fuel For Any Power Level!

Looking to make a serious step up in the horsepower department? The Sniper Dual 340 LPH or 450 LPH EFI pump modules would be an excellent choice. While the name includes EFI, these modules can be used as an upgrade for carbureted systems as well with the proper regulator. The innovative clamping system allows you to locate the module nearly anywhere in the tank while retaining your factory fuel level sending unit. The clamping system allows you to rotate the unit 360 degrees for easier clocking of the plumbing and wiring locations under your vehicle.

Features: Billet, anodized, laser etched flanges with 8AN ORB Return/Outlet and 6AN ORB vent The innovative clamping system allows you to locate the module nearly anywhere in the tank while retaining your factory fuel level sending unit Easy install – just drill a 4” hole in the top of the tank then use hand tools E85 compatible The dual pump design allows the pumps to be ran together or the second pump can be triggered additionally when you need it (Hobbs switch, Holley EFI auxiliary pump circuit, etc…) Units install in tanks from 7” – 12” deep Filter socks included
