Description
A very common failure of the 6.7L Common Rail Cummins and Duramax is that of the pressure relief valve. These relief valves are a simple spring that is designed to relieve pressure as it exceeds a predetermined pressure. Unfortunately, as pressure is continually applied to this spring, it fatigues and does not have the ability to maintain even stock pressures. Now, throw pressure boxes and other power adders into the mix that demand higher rail pressure, and this spring further fatigues, causing you to lose valuable rail pressure. This Rail Plug easily installs into the factory rail and eliminates the troublesome pressure relief valve to ensure you're getting the commanded rail pressure of your CP3 all the way to your injectors. Torque to 70 ft-lbs when installed.

About BD-Power

BD Diesel is known as one of the originators of diesel performance because theyve been there since the very beginning. Its by no coincidence that theyve been in the industry since 1972 where theyve seen competition come and go over the years. You could consider them a front to back organization in which they design and manufacture products ranging from Super B Turbo Kits and performance injectors for your Cummins to heavy duty transmissions, torque converters, and other transmission components for your Duramax to Positive Air Shutdowns and exhaust brakes for your Powerstroke and everything in between. Quite literally, there are VERY few components that BD does not build for nearly every light duty diesel application.

BD DIESEL PERFORMANCE

Originally founded in 1972 as Valley Fuel Injection that specialized in fuel injection rebuilding and calibrating, BD Diesel gained the most notoriety beginning in 1989 with the release of their first exhaust brake designed for Ram trucks with the acclaimed 12 Valve Cummins engine. BD would later rename Valley Fuel Injection to BD Diesel Truck Service and Performance Center that operates as an extension to BD Diesel Performance. Today, they operate out of a 65,000 square foot facility in Abbotsford, British Columbia and employ over 100 highly skilled individuals. They are constantly pushing the envelope with forward thinking products that not only fill voids in the marketplace, but also take existing products and push them to the next level.

BD DIESEL TRANSMISSION UPGRADES

Transmissions have a singular but ambitious challenge - to transfer all the torque from the diesel engine to the drive wheels. This must be accomplished while maintaining shift quality and minimizing NVH (Noise, Vibration, and Harshness). With stock or OE configurations, this capacity challenge is somewhat less than extraordinary. Comparatively, a high output diesel that develops 2-4 times the original engine torque and keeping stellar driving characteristics at this power level becomes a new feat. Utilizing the latest technology in CAD and FEA simulation, BD can predict and eliminate failures before they happen. The dedicated team of BDs Transmission and Torque Convertor Department are true experts in the development and analysis of the diesel transmission.

BD EXHAUST BRAKES

BD built its reputation on exhaust brakes starting in the early 90's with many casting designs for both engine and remote mount air actuated systems. Rugged cast-iron bodies with an offset stainless steel butterfly build peak efficiency quickly.

BD TURBO UPGRADES

The turbocharger industry is a special industry for BD and remains a key technological asset. When looking at BDs experienced staff, the majority of their key staff members have been developed in or around this technology. BD focuses on the customer's needs, whether it is fast turnaround, state of the art compressor wheels or turbine wheels, they look to deliver on the highest expectations. You can be assured that a BD turbocharger has been hand crafted to the greatest standards. Using precision lathes, milling equipment, honing machines, and inspection CMMs your turbocharger is continuously graded to exceed the OEMs specifications.

BD FUELING UPGRADES

Owing to its heritage as a diesel fuel systems specialist, BD Diesel Truck Service & Performance Center is a factory-certified Bosch, Stanadyne, Delphi and Zexel calibration and repair lab. They are one of a select few injection shops in North America to have Bosch Common Rail parts and an overhaul and testing franchise. BD Diesel rebuilds most all mechanical and electronically-controlled fuel pumps and injectors for diesel engine applications.

BD ELECTRONICS

Throughout the automotive industry, electronic technology has become an integral part of the OEM solution. Whether it is safety, performance, or driving improvements, BD Diesel Performance has developed a strong electronic department to focus strictly on this technology. By focusing on the core needs of the customer, they engineer out the possible product failures and maximize key features to deliver a top to bottom solution. Utilizing state of the art manufacturing equipment, BD maximizes value and minimizes time consuming tasks that inflate costs. Vehicle electronic technology will remain a key technology at BD Diesel Performance.

Fuel plug

"It serves its purpose. Easy installation"

Robert P. (4/5)

Top quality.

"Top quality."

BRIAN S. (5/5)

Fixed the rail pressure

"I had falling rail pressure above 2500 rpm and this fixed it from falling off and throwing a code everytime I hauled something heavy. Truck runs extremely smooth now at all speeds and ranges."

Kristopher G. (5/5)

Terrific

"I believe I bought one of these from you before. As usual, it shipped out quickly and arrived on time. I purchased another one so I can have two complete fuel rail to injector setups. One in service and one clean and ready to go. This way, I don't have much down time waiting on parts for my next injector swap and I don't have rush to clean or suspect this part or that part may not be clean enough. So now I will just switch out one setup and thoroughly clean/remanufacture the other, with the exception of the injector tube which will be new. So, be looking for an order of 6. 7l injector tubes in the near future. Again, thank you guys for being awesome!!!!"

Easy install

"Seems to work. No leaks and easy install."

William G. (5/5)

Big Difference!!!

"Great upgrade for the money with results that can be immediately felt. I’m pushing only 510 HP so not worried about injector failure just yet."

Q&A

Is it safe to use on an entirely stock 6.7?
Yes it would be ok on a stock 6.7 truck. No issues there. If you are having low pressure issues, this is one of the least expensive things to check of course. But it could also be related to injectors, injection pump, or fuel supply to the injection pump. -Sands
Is it safe to install a new fuel rail plug? From what I heard it isn’t due to the fact it “spikes� fuel pressure and I don’t know if that’s entirely true but I want to know if it is safe or not.
We have sold these to people with stock to highly modified trucks and have had ZERO failures or issues with excessive rail pressure. -Ben
What's the difference between the $51.00 plug and the $ 31.00 you sell for the 6.7 cummins? There is only one pressure relief so why the 20 something dollar difference?
Different manufactures ask different prices for their products is the best answer I can give you on this. I will also add that they are all constructed identically.- TL
