To make your LS1 transplant a little less painful, we put together these kits for you. If you already have a fuel pump in the tank, use the filter/regulator kit 910-12800. This kit includes a high pressure 255lph MSD in-line pump capable of 43 gph @ 40 psi or 39 gph @ 80 psi, a filter/regulator assembly, and all necessary fittings (including fuel rail fitting and hard-to-find -6 AN female to 5/16″ hose barb fitting). Pump draws only 5.4 amps and supports up to 500 horsepower. Pump features 3/8″ hose barb inlet and 5/16″ barb outlet. Hose and additional fittings sold separately. MSD pump requires the use of 5/16″ high pressure rubber hose with appropriate fuel injection hose clamps for the pressure side of the pump. New Vapor Guard hose, fittings and clamps shown below are now available for your one stop shop and to help make this install a snap.
