Fuel Delivery Components for Cummins ISX Single Cam

Fuel Pump Couplings

The fuel pump coupling is a small but essential part of the ISX fuel system. It connects the mechanical fuel pump to the drive system, ensuring efficient and vibration-free power transfer. A worn coupling can lead to poor pump performance or failure.

• Designed for direct fit on ISX Single Cam engines.

• Manufactured with durable materials to resist wear.

• Easy installation with OEM-level compatibility.

Fuel Shutoff Valves (Solenoid Valves)

Fuel shutoff valves are critical safety and control devices. On the ISX, these solenoid-operated valves allow operators to cut off the fuel supply instantly in case of an emergency or during engine shutdown.

• Available in 12-volt and 24-volt options.

• Built to OEM standards for ISX, QSX, and related Cummins platforms.

• Provide dependable sealing and fuel flow interruption when engaged.

Applications: Fleet vehicles, industrial equipment, and heavy transport applications using the ISX Single Cam engine.

Fuel Solenoids for ISX Engines

Solenoids are vital for controlling fuel delivery, working in tandem with the fuel shutoff valve to regulate the system. Cummins ISX solenoids are available in multiple voltage and configuration options:

• 12-Volt Single Pole Solenoid: Common for standard ISX fuel systems.

• 24-Volt Single Pole Solenoid: Supports heavy-duty setups requiring higher voltage.

• 24-Volt Two-Pole Solenoid: Offers enhanced connectivity for specialized ISX applications.

Key features:

• Precision winding for long service life.

• Corrosion-resistant housing for durability in harsh operating conditions.

• Designed for ISX, QSX, and legacy Cummins platforms such as NT855 and N14.

Seal Rings and Supporting Hardware

Rectangular Seal Ring

A small but critical component used in fuel shutoff solenoid assemblies. The seal ring prevents leaks and ensures tight sealing between solenoid and housing.

• Two required per solenoid.

• Designed to fit ISX, QSX, and related Cummins families.

• Resistant to heat, vibration, and fuel exposure.

Fuel Filters for Cummins ISX Single Cam

Fuel filters protect the ISX engine from contaminants such as dirt, rust, and water. Clean fuel ensures proper injector function, prevents wear on high-pressure pump components, and improves overall efficiency.

Standard Fuel Filter

• Designed specifically for Cummins ISX fuel systems.

• Protects high-pressure fuel injection components.

• Extended service intervals and consistent flow rates.

Fuel Filter & Water Separator

• Combines filtration with effective water separation.

• Larger size accommodates higher flow rates typical of ISX applications.

• Helps prevent injector damage caused by water contamination.

Fuel Filter Bases

The fuel filter base provides the secure mounting and fuel pathway for filter elements. On ISX engines, the base is compatible with both fuel filters and fuel-water separators.

• Machined for precision fit.

• Corrosion-resistant to withstand diesel fuel exposure.

• Designed for use with ISX and QSX Cummins engines.

Fuel Filter Tools & Accessories

Fuel Filter Removal Wrench

Removing fuel filters on the ISX can be challenging without the proper tool. A filter wrench ensures safe and damage-free removal.

• Adjustable to fit multiple filter sizes.

• Compatible with Cummins ISX and Detroit Diesel filters.

• Essential for routine filter replacement and servicing.

Racor Fuel-Water Separator Systems

Although designed for marine and industrial applications, Racor systems are widely used alongside Cummins ISX platforms in equipment requiring extra protection from fuel contamination.

Complete Separator Units

• Available in multiple capacities (500, 900, 1000 series).

• Provide advanced water separation and fuel filtration.

• Designed to extend engine life in challenging environments.

Replacement Filter Elements

• 2010, 2040, and 2020 elements available in 2-micron (brown top) and 30-micron (red top) ratings.

• Micron choice allows tailored filtration based on operating conditions.

• Designed for easy replacement without removing the entire unit.

Fuel Pressure Switches

Fuel and oil pressure switches provide vital engine monitoring. On Cummins ISX engines, these switches are used to protect the fuel system and alert operators of unsafe pressure levels.

• Available in 5 PSI, 10 PSI, 20 PSI, and 27 PSI make/break configurations.

• Designed with 1/8 NPT threading for compatibility.

• Durable construction for high-vibration ISX operating environments.

Gauges for Fuel System Monitoring

Reliable gauges allow operators to track pressure and system performance at a glance.

• Mechanical Gauges: Rugged and dependable with alarm options.

• Electrical Gauges: Available in 12-volt and 24-volt versions.

• Designed for integration with ISX control panels and monitoring systems.
