The FHST is sold separately. This kit includes all necessary hardware, brackets, fittings, hose, and wiring components to complete the installation without cutting, drilling, or permanent modifications to the vehicle.\u003c\/p\u003e\n\n\u003cp\u003eThe OEM fuel pump is repurposed to keep the surge tank full, with excess fuel returning to the OEM fuel tank.
