New for the Holley Sniper EFI 2 is the optional Power Distribution Module (PDM). This cost-effective and optional accessory isolates the core of your EFI and ignition wiring into one, easy-to-use location. Simply slide the stripped wire ends under the positive lock connector and tighten down the set screw. Battery and a switched 12-volt source is all that’s required from your vehicle to power the PDM and your Sniper EFI.
The Holley Sniper EFI (Self-Tuning Kit) is a fuel delivery method using fuel injection in place of a standard carburetor. Ideally suited for classic cars with carburetors, the unit regulates more precisely the flow of fuel into the engine, eliminating cold starts, flooding, and vapor lock.

- Engine is a 4, 6 or 8 cylinder
- Engine has a 4 barrel, 4150 style flange intake manifold*

- Any 4150 flange intake manifold will work. Make sure to use included gasket to seal the throttle body to the intake manifold and ensure
that there are no vacuum leaks.
Fuel System Requirements:
The Sniper 2 EFI system requires a high pressure fuel pump capable of operating at 60 psi. When selecting a pump and lines, be sure each component is designed to perform at high pressure. Holley offers a variety of fuel pumps, hoses and accessories to complete your installation. For best results, Holley strongly recommends an in-tank pump. Installing the fuel pump in the tank results in quieter operation, less chance of cavitation and a reduction in pump temperature. If mounting the pump in the tank is not an option, install the pump as close as possible to the tank, within 2-feet of fuel tank feed is recommended. Once the fuel system is installed, checking the fuel pressure at the regulator is recommended.
Holley offers Sniper 2 EFI kits that include a complete fuel system, eliminating the hassle of selecting individual fuel system components.
