This set of 8 tools is designed to help locate injectors with high return rates, making it easier to troubleshoot no-start conditions. Proudly made in the USA, this professional-grade tool ensures durability and reliability for all your automotive needs. ## Description These tools are a "must have" for anyone who works on the 6.4L common rail fuel systems. When a 6.4L engine will not start, one of the first things to check is fuel rail pressure. If the pressure is less than 4,000 PSI, one of the most likely causes is a defective injector that is returning excess fuel back to the tank. A return flow volume test will verify if excessive return flow is the problem. These caps are then used to identify the individual cylinder that is at fault. The injection lines are removed from the injectors and a cap is installed on the fuel rail in place of each injection line. When the cylinder with the offending injector is capped, the rail pressure will rise and the truck will start. In some cases it can be highly advantageous to have multiple caps, because several injectors that return slightly too much fuel can have the same effect as a single injector with extremely high return flow. A block off tool can also be used temporarily in the case of a broken injection line or failed injector and is a good thing to have in your emergency kit. When an injector malfunctions on a common rail engine damage to a piston or cylinder can occur very rapidly. When a common rail engine begins to misfire and blow excessive white smoke, the owner is highly advised to turn the engine off and call a tow truck to prevent major engine damage from occurring. An alternative would be to temporarily cap the injector for that cylinder for a short period. When working on high pressure fuel systems, always educate yourself first by reading appropriate factory service information, use common sense, and, above all, WEAR SAFETY GOGGLES! ## Features - A "must have" for anyone who works on 6.4L - Very helpful for No-start diagnostics - Compatible with Powerstroke 6.4L 2008 - 2010 - Most often used for locating an injector with high return rate that is causing a no-start condition - Made in the USA ## Images ![AccurateDiesel 6.4L Diesel Injector Block-Off Tool/Cap (Set of 8) - Compatible with Powerstroke/Ford - Image 1](https://m.media-amazon.com/images/I/71zd6ozs5XL.jpg) ![AccurateDiesel 6.4L Diesel Injector Block-Off Tool/Cap (Set of 8) - Compatible with Powerstroke/Ford - Image 2](https://m.media-amazon.com/images/I/91fe98EHgSL.jpg) ![AccurateDiesel 6.4L Diesel Injector Block-Off Tool/Cap (Set of 8) - Compatible with Powerstroke/Ford - Image 3](https://m.media-amazon.com/images/I/81jFm3KdY3L.jpg) ![AccurateDiesel 6.4L Diesel Injector Block-Off Tool/Cap (Set of 8) - Compatible with Powerstroke/Ford - Image 4](https://m.media-amazon.com/images/I/81pBq6jSj4L.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/46562414-accuratediesel-6-4l-diesel-injector-block-off-tool-cap-set](https://www.desertcart.pl/products/46562414-accuratediesel-6-4l-diesel-injector-block-off-tool-cap-set) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-23*
