Injector Block Off Tool Fits for 6.7 Cummins 2003-2022, Duramax 2001-2022, Ford 2008-2022 Diesel Engines, 12|14|16|18|20 MM Rail Fuel Line Cap,

Wide Compatibility - Fuel Injector Caps designed for fuel rail diagnostics in 2003-2022 Cummins, 2001-2022 Duramax, and 2008-2022 Ford engines. Efficient Functionality - Effectively blocks the fuel supply to cylinders or seals the common rail pipe, aiding in the identification of faulty diesel injectors and diagnosing engine knock sounds. Easy-to-Follow Instructions - Identify the faulty cylinder by removing the diesel fuel injection line from one cylinder at a time and installing the cap on the fuel rail. Increased fuel pressure indicates the faulty injector. High-Quality Construction - Made from full carbon steel with an anti-rust finish. These fuel line caps feature a galvanized surface for durability and resistance to breakage and deformation, ensuring a long service life. Important Note - Multiple fuel pressure block-off tools can be helpful, as several injectors returning small amounts of fuel can mimic the symptoms of a single injector returning excessive fuel.
