GIVING AN OLD, WORN-OUT 12V CUMMINS A FEW FUELING UPGRADES

- Jacob White

While the 12V Cummins might be considered a dinosaur to most in the diesel business, there are still plenty of them out on the road, working job sites and hauling cattle to the auction. The 12V Cummins takes us back to a simpler time when unhackable computers controlled our engines’ running parameters, and all it took to make power was a little more fuel and the air to support it. The 12V Cummins was an incredible platform back in its day, and it can still offer great driving characteristics today with the proper setup. The mechanical P7100 injection pump had endless upgrades to supply fuel to the engine to make just about whatever power levels you wanted. They’ve lost some of their popularity because of later common rail technology, but the dinosaurs aren’t dead.

In the past, setting up a 12V to do just about everything was a bit of a challenge. Sure, the injection pump could be built to put out a ton of fuel. The fuel plate and delivery valves could adjust how that fuel was supplied to the engine. However, it was always an all-or-nothing set up that had to then be controlled by your right foot. Today, thanks to the folks at Attitude Performance Products, controlling your fueling output is just a couple clicks away with their new Adjuster—a fully adjustable fuel plate housing that allows complete in-cab P-pump fueling control with the turn of a knob.
