Sniper EFI Returnless Self-Tuning Fuel Injection Systems

Want to convert your carbureted vehicle to Sniper EFI, but don't like the idea of mounting an external fuel pump? Look no further! Sniper EFI Master Kits combine their self-learning throttle body, with an easy-to-install in-tank retrofit returnless 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 drop-in Master Kits make plumbing your Sniper EFI installation as hassle-free as possible: simply cap the regulator on the Sniper EFI throttle body with the provided -6 AN cap; then safely route the Vapor Guard fuel line along the chassis back to the diecast fuel hat—and the job is finished.
