Looking to make a serious step up in the horsepower department? The Holley Dual 450 LPH EFI Pump Module 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 ride.
