Gravedigger Returnless Port Injection Fuel System

The Graveyard Performance Gravedigger Returnless Port Injection Fuel System is a carefully curated kit designed to enhance fuel delivery for Mazdaspeed 3 and 6 models. This system offers a budget-friendly pathway to port injection, providing the capability to support up to 600 wheel horsepower with appropriate supporting modifications. For power levels exceeding this, a fuel cell or surge tank will be necessary. The kit connects to the OEM fuel line at the firewall and returns to the High Pressure Fuel Pump (HPFP) to feed the Direct Injection (DI) injectors. Included components are Alpha Injection Clinic 1000CC Injectors and Graveyard Performance -6 PTFE Custom Fuel Lines. Optional components available for purchase include Aeromotive 325LPH Stealth or AEM 340LPH in-tank fuel pumps, and MoTiv Reflex Lite or MoTiv Reflex Lite with Plug and Play Harness fuel controllers. The fuel rail/manifold is selected via a dropdown menu. Installation is rated as expert difficulty and is estimated to take approximately 5 hours, requiring a full socket set, fuel line tools, and electrical tools. Extensive wiring and manifold installation are necessary. Due to the complexity, professional installation is recommended.
