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 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). 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.
