Each cap features internal thread sizes and thread intervals of 1.5, with inner diameters corresponding to each size (12mm, 14mm, 16mm, 18mm, and 20mm).<\/li><li>Vehicle Compatibility \u2013 The fuel caps are designed to fit various diesel engines. The 12mm fuel cap fits Ford 6.4L (2008-2010). The 14mm fuel cap fits Ford 6.7L (2011-2022), Cummins 5.9L (2003-2009), Duramax 6.6L (2001-2005 and 2017-2022). The 16mm cap fits 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 with similar-sized fuel line nuts.<\/li><li>High-Quality Construction - These injector rail fuel line cap block-off tool sets are made from full carbon steel for enhanced durability and long service life.<\/li><li>Efficient Functionality \u2013 These diesel rail fuel injector block-off caps are designed to effectively block fuel supply to cylinders or seal the common rail pipe. This helps in diagnosing engine issues, such as identifying faulty diesel injectors or troubleshooting engine knock sounds by isolating each cylinder.<\/li><li>Easy-to-Follow Instructions \u2013 To use, simply 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 the faulty injector. Multiple block-off tools can be useful, as multiple injectors returning small amounts of fuel may mimic symptoms of a single injector with excessive fuel return.<\/li><\/ul>        <\/div>\n    <\/div>\n\n    <div class=\"aawp-product__footer\">\n\n        <div class=\"aawp-product__pricing\">\n            \n            \n                    <\/div>\n\n                <a class=\"aawp-button aawp-button--buy aawp-button aawp-button--green\" href=\"https:\/\/www.amazon.com\/dp\/B0DLWW2LQF?tag=romanceunivers-20&#038;linkCode=osi&#038;th=1&#038;psc=1&#038;keywords=injector%20cap\" title=\"View Product\" target=\"_blank\" rel=\"nofollow noopener sponsored\">View Product<\/a>\n            <\/div>\n\n<\/div>\n\n            \n            \n<div class=\"aawp-product aawp-product--horizontal aawp-product--style-standard aawp-product--bestseller aawp-product--ribbon\"  data-aawp-product-asin=\"B0F19FTQDQ\" data-aawp-product-id=\"5909854\" data-aawp-tracking-id=\"romanceunivers-20\" data-aawp-product-title=\"Mysttoo 5PCS Common Rail Fuel Injector Block-Off Caps - 12|14|16|18|20mm Diesel Fuel Line Tester Cap Fits for 2003-2022 Cummins  2001-2022 Duramax & 2008-2022 Ford Engines Replace# 10810\" data-aawp-geotargeting=\"true\">\n\n    <span class=\"aawp-product__ribbon aawp-product__ribbon--bestseller\">Rank No. #3<\/span>\n    <div class=\"aawp-product__thumb\">\n        <a class=\"aawp-product__image-link\"\n           href=\"https:\/\/www.amazon.com\/dp\/B0F19FTQDQ?tag=romanceunivers-20&linkCode=osi&th=1&psc=1&keywords=injector%20cap\" title=\"Mysttoo 5PCS Common Rail Fuel Injector Block-Off Caps - 12|14|16|18|20mm Diesel Fuel Line Tester Cap Fits for 2003-2022 Cummins; 2001-2022 Duramax & 2008-2022 Ford Engines, Replace# 10810\" rel=\"nofollow noopener sponsored\" target=\"_blank\">\n            <img decoding=\"async\" class=\"aawp-product__image\" src=\"https:\/\/m.media-amazon.com\/images\/I\/41H0e6bsZYL._SL160_.jpg\" alt=\"Mysttoo 5PCS Common Rail Fuel Injector Block-Off Caps - 12|14|16|18|20mm Diesel Fuel Line Tester Cap Fits for 2003-2022 Cummins; 2001-2022 Duramax & 2008-2022 Ford Engines, Replace# 10810\"  \/>\n        <\/a>\n\n            <\/div>\n\n    <div class=\"aawp-product__content\">\n        <a class=\"aawp-product__title\" href=\"https:\/\/www.amazon.com\/dp\/B0F19FTQDQ?tag=romanceunivers-20&linkCode=osi&th=1&psc=1&keywords=injector%20cap\" title=\"Mysttoo 5PCS Common Rail Fuel Injector Block-Off Caps - 12|14|16|18|20mm Diesel Fuel Line Tester Cap Fits for 2003-2022 Cummins; 2001-2022 Duramax & 2008-2022 Ford Engines, Replace# 10810\" rel=\"nofollow noopener sponsored\" target=\"_blank\">\n            Mysttoo 5PCS Common Rail Fuel Injector Block-Off Caps - 12|14|16|18|20mm Diesel Fuel Line Tester Cap Fits for 2003-2022 Cummins; 2001-2022 Duramax & 2008-2022 Ford Engines, Replace# 10810        <\/a>\n        <div class=\"aawp-product__description\">\n            <ul><li>These 5 pieces\/full set of caps used to block off the fuel rail during fuel pressure diagnostics, works on 2003-2022 Cummins, 2001-2022 Duramax and 2008-2022 Ford Powerstroke engine.

Each cap is designed with internal thread sizes of 1.5, and inner diameters matching 14mm.<\/li><li>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.<\/li><li>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.<\/li><li>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.<\/li><li>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.<\/li><\/ul>        <\/div>\n    <\/div>\n\n    <div class=\"aawp-product__footer\">\n\n        <div
