The Sniper 2 EFI returnless drop-in module with PDM swaps a 4150-flange carburetor for a complete self-tuning fuel injection system, built around an in-tank/returnless fuel delivery setup. The included Power Distribution Module (PDM) isolates the core EFI and ignition wiring into one location, so only a battery and switched 12-volt source are needed to power the PDM and Sniper EFI.
