Introducing Sniper EFI Master Kits, with a Returnless Drop-in Retrofit Fuel Module. These kits combine the Sniper EFI Self Learning Throttle Body, with an easy to install In-Tank Retrofit Returnless Fuel Module, 20 ft. of Earl's Vapor Guard Fuel Hose, and the required fittings. The included fuel system places a 340 LPH fuel pump in the tank, which can easily be accomplished with basic hand tools. 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. Simply cap the regulator on the Sniper EFI throttle body with the provided -6 AN cap, safely route the Earls' Vapor Guard fuel line along the chassis to the die cast fuel hat, and the job is finished.
