Cummins 5.9L/6.7L Injector Fuel Tubes


  • Product Description

           100% New OEM 5.9L Cummins Bosch Fuel Tubes.  This is a stock replacement part, it will not provide any extra performance. It is recommended to replace your fuel tubes as you replace your injectors. 

           Fuel tubes supply injectors with high-pressure diesel fuel.  Reusing old fuel tubes can cause leaks, resulting in contaminated fuel going into your injectors.  This will cause early failure of your injectors.

  • Why a Dr. Performance module?

    • You got a new diesel truck advertised with supercar levels of torque and power. But does it really feel like it? You step on the pedal, but your truck decides to wait a few seconds before giving you what you asked for. You know what I’m talking about – turbo lag. And those few seconds feel like an eternity when you have a fifth wheel behind you and you’re trying to pass the schmuck who has been going 8 under the speed limit since you got back on the highway (after your wife and kids conveniently needed their 3rd bathroom break in the last hour).

      Okay, maybe that isn’t your exact situation. Or maybe it hit a little too close to home. Regardless, I think we can all agree that we aren’t getting all that power we paid for. I’ve got some good news for you. That power you were promised is indeed there. You just have to unlock it.

      And no – I’m not about to tell you to delete your truck or download a tune that will void your warranty and put excessive strain on your nice new truck. I’ve got something better. The Dr. Performance Pro Performance Module.

  • FAQs

    • Q: Will it damage my transmission?
      A: No. Dr. Performance Pro Performance Modules will actually give you a smoother and cleaner running powertrain, and in many cases will improve transmission performance due to not needing to shift down as often. Dr. Performance Modules do not over-ride safety parameters.


      Q: Do I need gauges or any other modifications?
      A: Nope! Unlike some modifications that require monitoring devices, the Dr. Performance module works within your trucks factory safety parameters. Our module is designed to work on completely stock trucks.

      Q: How hard is it to install?
      A: Not hard at all! Most our modules can be installed in 20 minutes or less with little to no tools required. Our modules use factory OEM plugs and plug inline with the fuel pressure sensor and on some models the boost sensor as well. Installation varies from truck to truck, but all can be installed yourself with little to no mechanical knowledge. All modules come included with detailed installation instructions with pictures. We also have all installation instructions here. We are available 24/7 via phone if you run into any issues! (800) 406-5257


      Q: Is it safe to tow with?

      A: Absolutely! If anything, one might argue that it’s safer to tow with our module. With our module you can tow as you normally would. Make sure to use your trucks tow/haul mode when in tow!


      Q: How much power will I actually gain?
      A: On average we see gains of 30-90 hp to the wheels and up to 120 lb-ft of torque. Keep in mind these modules provide functional low to midrange power in the daily driving and towing RPM range. A dyno measures power at wide open throttle – it doesn’t measure daily driving improvements like rolling into the throttle and holding gears better. These modules make a difference in the 99% of driving situations when you aren’t at wide open throttle.


      Q: Why should I get a module instead of a tuner?

      A: Different strokes for different folks! If you are looking to turn your truck into race car, maybe a tuner is better suited for. Tuners focus on top end power. Our module focuses on the low to mid-range RPMs where most all of your driving is spent. Tuners flash your ECM, void your warranty, and produce additional wear and tear on your engine. The Dr. Performance Module is a safe way to gain power all without sacrificing your warranty.
