Special Features

  • Product Specifications - This diesel common rail fuel injector block-off cap set includes 4 pieces of 20mm caps (M20 x 1.5). Each cap is designed with internal thread sizes of 1.5, and inner diameters matching 20mm.
  • High-Quality Construction - The injector rail fuel line cap block-off tools are crafted from full carbon steel, providing superior durability and a long service life.
  • Efficient Functionality - These block-off caps effectively seal the common rail pipe or block fuel supply to cylinders, making it easier to diagnose engine issues. They are particularly useful for identifying faulty diesel injectors or troubleshooting engine knock sounds by isolating individual cylinders.
  • Easy-to-Follow Instructions - For use, remove the diesel fuel injection line from one cylinder at a time and install the corresponding cap on the fuel rail. Increased fuel pressure indicates a faulty injector. Multiple block-off tools may be helpful, as several injectors returning small amounts of fuel could mimic the symptoms of a single injector with excessive fuel return.
  • Vehicle Compatibility - These fuel caps are compatible with various diesel engines. The 12mm fuel cap fits Ford 6.4L (2008-2010). The 14mm cap fits Ford 6.7L (2011-2022), Cummins 5.9L (2003-2009), and Duramax 6.6L (2001-2005 and 2017-2022). The 16mm cap is suitable for Cummins 6.7L (2019-2022). The 18mm cap fits Duramax 6.6L (2011-2016). The 20mm cap fits Cummins 6.7L (2007-2018) and Duramax 6.6L (2006-2010). These caps are also compatible with other vehicles using similar-sized fuel line nuts.
