Product Description
Holley Sniper EFI Quadrajet™ Master Kits combine the Sniper EFI Self Learning Throttle Body with an easy-to-install, in-tank, retrofit returnless Fuel Module, 20 feet of Earl's Vapor Guard fuel hose, and all of the required fittings you need. The included fuel system places a 340 LPH fuel pump in the tank, which can easily be accomplished with basic hand tools. The Sniper EFI Quadrajet system retains the same great features as the Sniper EFI 4bbl version. This includes four 100 lb/hr injectors, built in timing control (when used with a HyperSpark or Pro Billet distributor), a 3.5" full color touchscreen, and much more! The throttle body will support up to 500 naturally aspirated horsepower. In addition to all of these tried and true features, the Sniper EFI Quadrajet system will fit most stock air cleaners and offers multiple fuel inlet configurations that allow for a stock appearing installation. The returnless drop-in master kits make plumbing your Sniper EFI installation as hassle free as possible by locating the fuel pressure regulator in the fuel tank, thus eliminating the need to run a fuel return line from the engine bay, back to the fuel tank.
