At Custom Diesel, we know what it's like to be passionate about diesel, horsepower and reliability. That's why we offer a full line of high-quality diesel injectors, injector pumps and replacement parts for your 7.3 Powerstroke fuel system. Adding upgraded fuel injectors can increase horsepower. In fact, many diesel owners start with injectors when enhancing the Powerstroke's fuel system. However, when adding an injector, you should also consider upgrading the fuel pump. Your Powerstroke's fuel pump is an integral part of the fuel system. The oil pump actuates your fuel injectors and directly impacts the pressure and duration of the injection. In many cases, the factory fuel pump cannot keep up with the demands of an upgraded injector, which leads to lower pressure, less power and more smoke. Custom Diesel is as dedicated to the performance of your diesel as you are. We offer a large variety of diesel performance parts that you can use to improve your diesel's operations, power and appearance. Contact us to learn more about the products we offer.
