Cummins QSX Engine Parts – Fuel Pump & Fuel System Section

The Cummins QSX fuel system delivers precise fuel control, pressure, and flow to support the engine’s high-efficiency combustion design. At the core of this section, the Cummins Fuel Pump Coupling ensures a secure mechanical connection between the drive and the fuel pump, maintaining consistent synchronization for optimal fuel delivery. Supporting the system are Fuel Shutoff Solenoids available in both 12- and 24-volt configurations. These components play a crucial safety role by immediately stopping fuel flow when the ignition is turned off or during an emergency shutdown, preventing fuel leaks and overrun conditions.

For added durability and sealing performance, the Rectangular Seal Rings are installed on each solenoid to prevent fuel seepage and air entry. The Fuel Filters and Fuel-Water Separators in this section ensure that only clean diesel reaches the injectors, protecting the fuel pump and combustion system from contaminants. Available in multiple micron ratings, these filters effectively remove dirt, water, and particulates that can cause injector wear or poor performance. The Fuel Filter Base supports the assembly, while Racor-style Replacement Filters (2010, 2040, and 2020 series) offer dependable filtration in both 2- and 30-micron versions.

Additional support components include Fuel Filter Removal Wrenches, Fuel Pressure Switches (5–27 PSI), and 24-Volt Solenoids for auxiliary systems. Diesel Pro Power provides premium aftermarket components that match the quality, fit, and reliability professionals expect—keeping Cummins QSX engines performing with clean fuel delivery, reliable shutdown operation, and extended injector life.
