TamerX Diesel Fuel Injector Cap / Block-Off Tool Set for 6.4L Powerstroke, 6.6L Duramax, 5.9L & 6.7L Dodge/Cummins Applications 2001-2017 Part# TXCT-PKG2
APPLICATION:
- MAKE: Ford, GMC/Chevrolet, Dodge/Cummins
- ENGINE: 6.4L Ford Powerstroke, 6.6L Duramax Diesel (LB7, LLY, LBZ, LMM, LGH, LML), Dodge/Cummins 5.9L & 6.7L
- YEAR: 2001-2017
Learn More ↠This set includes 4 common sizes of diesel injector caps/block-off tools, giving you the versatility to work on and diagnose fuel system issues on Powerstroke, Duramax, and Cummins engines.
The TamerX TXCT-PKG2 Diesel Fuel Injector Cap/Block-Off Tool Set includes the following tools:
1- 12mm Cap for 2008-2010 6.4L Ford Powerstroke applications
1- 14mm Cap for 2001-2005 6.6L Chevrolet/GMC Duramax applications (LB7 & LLY) and 2003-2007 5.9L Dodge/Cummins applications
1- 16mm Cap for 2011-2016 6.6L Chevrolet/GMC Duramax applications (LGH & LML)
1- 18mm Cap for 2006-2011 6.6L Chevrolet/GMC Duramax applications (LBZ & LMM) and 2007-2017 6.7L Dodge/Cummins applications
This diesel fuel injector cap/block-off tool set is a toolbox essential for everyone working on Duramax, Powerstroke, and Dodge/Cummins fuel systems.
When a diesel engine fails to start, your first troubleshooting step should be to check fuel rail pressure. If the pressure is low, the most likely culprit is a defective diesel fuel injector returning excess fuel back to the tank. A return flow volume test will allow you to determine if excessive fuel return flow is the issue.
To identify the individual cylinder that is at fault, you will use this cap/block-off tool. The diesel fuel injection line is removed from one cylinder at a time and the cap is then installed on the fuel rail in place of each injection line. When the bad injector is blocked off, the fuel pressure at the rail will increase and your engine will start.
In some situations, it can be useful to have multiple block-off tools, because multiple diesel injectors returning a small amount of diesel fuel will display the same symptoms as an individual diesel injector returning an excessive amount of fuel.
The diesel injector cap tool can also be used for diagnosing engine knocking sounds that could possibly be caused by a diesel injector or a single cylinder issue, especially on engines where you can't use a scan tool or if a scan tool is unavailable. -

The TamerX Diesel Fuel Injector Cap / Block-Off Tool for 2001-2005 6.6L Chevrolet/GMC Duramax LB7, LLY is a toolbox essential for everyone working on common rail fuel systems.
When a common rail engine fails to start, your first troubleshooting step should be to check fuel rail pressure. If the pressure is under 5,000 PSI (on a 6.6L engine), the most likely culprit is a defective diesel fuel injector returning excess fuel back to the tank. A return flow volume test will allow you to determine if excessive fuel return flow is the issue.
To identify the individual cylinder that is at fault, you will use this cap/block-off tool. The diesel fuel injection line is removed from one cylinder at a time and the cap is then installed on the fuel rail in place of each injection line. When the bad injector is blocked off, the fuel pressure at the rail will increase and your engine will start.

Fuel System DetailsHigh-pressure common-rail injection technology has revolutionized the diesel industry. Over the last decade, it has allowed engine builders to run higher injection pressures (as much as 29,000 psi in the new LML Duramax and 6.7L Powerstroke) in order to increase efficiency, while greatly reducing emissions. Use of the common-rail system has also facilitated multiple injection events (making diesels quieter). The icing on the cake is that these cleaner-burning engines produce much more power than their predecessors.
CP3 Primary Function
The CP3 injection pump’s sole function is to create and regulate high-pressure fuel (it’s not timed with the engine’s crankshaft and camshaft). The fact that the CP3 came from Bosch’s heavy-duty line of injection pumps also speaks to its great reliability, as it was designed to play a vital role in million-mile engines.
