Generation III and IV small blocks are perhaps the most popular LSx engines for swapping--and the powerful GM V8s require equally effective fuel delivery. Summit Racing™ universal LS-style fuel systems incorporate both the fuel filter and regulator into one efficient, affordable unit. These 255 lph fuel pumps channel a precise 58 psi of juice to the "dead head" fuel rails inlet, returning any excess from the filter back to your tank. It's a system very similar to those used in factory LS performance cars, a simple fuel solution for car and truck owners who jettison their stock powerplant for a coveted LS. Summit Racing™ universal LS-style fuel systems also include 20 ft. of braided fuel line, as well as -6 AN inlet and outlet fittings in a black or blue anodized finish. (The kits are intended for use with a fuel cell or modified/aftermarket tank with AN outlets and returns.) Summit Racing™ also offers the filter and fittings in a smaller kit for those who don't need the entire system.
