Sniper 2 EFI Master Kit Returnless Retrofit

The Sniper 2 EFI Master Kit Returnless Retrofit from Holley is a comprehensive fuel injection solution designed for automotive enthusiasts looking to upgrade their carbureted or older fuel-injected engines. This kit is ideal for street machines, hot rods, and restorations, particularly in situations where space is limited or aesthetic considerations prevent the use of traditional return-line fuel systems.

The returnless design of the Sniper 2 platform simplifies installation by eliminating the need for a return line, thereby reducing clutter under the hood. This system regulates fuel pressure at the pump rather than at the injectors, allowing for a single feed line. The kit includes an in-tank pump module, precision fuel injectors, a high-resolution ECU with built-in harness connectors, and all necessary sensors and wiring for a plug-and-play installation.

With its self-tuning algorithm, the Sniper 2 EFI adapts to changing ambient conditions and load transitions, providing optimal performance. The integrated data logging capability allows users to monitor real-time fuel trims and engine metrics through compatible diagnostic tools or smartphone apps. This makes it an excellent choice for those looking to enhance their vehicle's performance while maintaining compatibility with modern fuel formulations.
