10810 Injector Rail Fuel Line Cap Set - 5 Pcs Rail Fuel Injector Block-off Cap Tools- Fits for 2003-2022 Cummins, 2001-2022 Duramax, and 2008-2022 Ford engines fuel pressure diagnostics.
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.
