Fuel pins are used in diesel trucks and tools. Cummins and Dodge Ram truck owners have discussed the benefits of fuel pins from Denny, Hungry Diesel, and BD Diesel Performance. Hungry Diesel fuel pins are said to produce a big puff of black smoke, while the M&H M2 pin is designed for stock fueling. Fuel pins are also used in tools such as the Milwaukee M12 pin nailer, which is a reliable tool for finish carpenters and cabinet installers. While some users have speculated about the possibility of a fuel pin nailer, others have pointed out that the nailer's small size and use of nitrogen tanks make a fuel version unnecessary.

What You'll Learn
The Hungry Diesel fuel pin
If you are looking for a performance fuel pin, The Hungry Diesel fuel pin is a great option. It offers more power and, depending on the setup, any added smoke can be cleaned up with minor star wheel adjustments. This is minimal to begin with when using a THD pin.
One user reported that they had just installed their new Hungry Diesel fuel pin and noticed a big difference. They turned the full fuel screw in 2 turns and ran the star wheel about 3 turns up. This resulted in a big puff of black smoke, but the turbo started spooling and the smoke cleared up, leaving only a light trail. The user suggested that to completely eliminate the smoke, they would need to make some additional changes.
Another user compared the Hungry Diesel pin to the Denny T #2 and found that the Hungry Diesel offering provided the best fit for them. They also mentioned that the Hungry Diesel and BD Diesel Performance pins are almost identical, with some minor differences in the ramp design.

Denny T #2
Users who have installed the Denny T #2 fuel pin have reported positive experiences. One user mentions that they have spent time with the Denny T #2, the stock in various positions, and The Hungry Diesel (THD) offering, and they found the THD option to be the best fit for them. This suggests that the Denny T #2 fuel pin provides noticeable improvements in performance, but the THD option may offer even better enhancements.
Another user mentions that they don't have a fuel pin in their trucks, and they run great without any issues. They question the need for a fuel pin, as in their experience, the engine runs properly without it. However, they acknowledge that some people might prefer the extra fuel and the smoke that comes with it.
When considering the Denny T #2 fuel pin, it is important to keep in mind that it might require some adjustments to minimise added smoke. One user mentions that they had to make minor star wheel adjustments to reduce smoke when using a performance fuel pin. Therefore, if you are looking for increased power without added smoke, the Denny T #2 fuel pin might require some fine-tuning to achieve the desired results.
Overall, the Denny T #2 fuel pin appears to be a popular option for those seeking performance fuel pins for their Cummins Diesel engines. It offers increased fuel flow, resulting in more power. However, it may also produce added smoke, which can be minimised through adjustments. For those seeking the best possible performance, exploring multiple options and making the necessary tweaks might be necessary to find the ideal setup.

Stock boost pin
A stock boost pin is a tuning part for a Bosch VE injection pump. The standard Bosch guide pin has an off-centre conical ramp that gives different profiles depending on its orientation. It is designed to restrict fuel delivery until boost pressure is added to the engine, ensuring there is sufficient air to burn the fuel.
A modified boost pin replaces the standard guide pin, allowing the pump to access full fuel delivery given sufficient boost pressure, which improves the vehicle's performance. The boost pin is based on tuning products made for the 1st Generation Dodge Ram, allowing more travel from the internal workings of the Bosch VE injection pump.
While the standard guide pin offers good improvements in performance, it does not allow the VE pump to reach its full potential. The modified boost pin improves the vehicle's performance by allowing the pump to access full fuel delivery.
Some users have expressed a preference for the Hungry Diesel fuel pin, which offers more power. The Denny T #2 pin is also mentioned as a good option, providing more fuel right from off-idle to TEL. The M&H M2 pin is designed for stock fuelling down low, with more fuel available when it is generally needed, up top.

BD Diesel Performance Pin
The BD Diesel Performance Pin is a fuel pin kit for diesel engines. It is designed to improve engine performance and increase horsepower and torque. The kit includes a fuel pin and a governor spring, which work together to enhance the vehicle's overall performance.
The BD Diesel Performance Pin is a popular choice for those seeking to improve the power and responsiveness of their diesel engines, particularly in older model Cummins engines. Users have reported significant improvements in top-end speed, with gains of 10-15 miles per hour, as well as enhanced low-end torque. The kit has also been noted to reduce turbo lag, a common issue with other high-performance modifications.
One notable advantage of the BD Diesel Performance Pin is its cost-effectiveness. Despite its performance enhancements, it does not negatively impact fuel economy. This makes it a desirable option for those seeking increased power without sacrificing fuel efficiency. The kit also receives praise for its clear and concise installation instructions, making it accessible for those with limited experience in injection pump modifications.
However, there are some considerations to keep in mind. One user reported that after approximately 5,000 miles, the fuel pin had seized in the pump and required cleaning and reinstallation. This highlights the importance of regular maintenance and monitoring to ensure optimal performance and longevity of the fuel pin. It is worth noting that proper maintenance and care can help extend the lifespan of the pin and prevent similar issues.
Overall, the BD Diesel Performance Pin is a well-regarded option for those seeking increased performance, improved torque, and reduced turbo lag in their diesel engines. Its cost-effectiveness and ease of installation make it a popular choice, but it is important to prioritize regular maintenance to ensure optimal results.

M&H M2 pin
The M&H M2 fuel pin is designed for stock fueling down low, with more fuel available up top, where it is generally needed. The M2 pin is intended to keep as much fuel as possible out of the pump until the last second.
The M2 pin is recommended for manuals if you're going to be towing anything. However, some users have noted that the M2 pin does not have as deep a cut as other options, such as the Denny T #2 pin or the M3 pin, which is recommended for automatics.
Users have also suggested that the M2 pin may not provide enough fuel at the bottom end, and that it may be preferable to remove fuel from the bottom. Additionally, there are concerns that the M2 pin may cause lag and excessive black smoke due to potential issues with the bleed-off when the pin is supposed to return to "low fuel".
If you are looking for more power, the Hungry Diesel pin or the BD Diesel Performance Pin are other options to consider. The BD pin, in particular, has a flat ramp as opposed to a progressive ramp, which allows for a much smoother transition into fueling.
