At WEAPON-X Motorsports, we're always pushing the envelope to develop new products to further the power gains on the new direct injection GM vehicles.  We bring you our custom line pump fuel kits, complete with PnP harness, return, and optional flex sensor!  Our custom made kits have some innovative features to raise the bar for performance and safety too.  The need arises from low fuel pressure and low line pressure leads to low rail pressure.  Much like an injector, the less pressure on the back side of the high side mechanical pump can starve it causing rail pressure to drop, knock retard to occur, and motors to blow.  

High Flow Direct Injection for GM Generation V V8 Applications 

These are designed for the new GM LT series engines. These supply the needed fuel flow for high horsepower applications and only come on when the more fuel is needed and are E85 compatible allowing higher output engines to take advantage of the octane of E85 fuel.

Stage 1 is your budget returnless kit for those 800whp ranges with a set regulator

Stage 2 is the full return kit for more fuel supply with E85 with an adjustable regulator
