Fuel Pump & Fuel System Components for Cummins M11 Engines

The Cummins M11 engine is a reliable workhorse designed for both industrial and marine applications, and its performance depends heavily on a properly maintained and efficient fuel system. From the injection pump to the shutoff solenoid, every fuel component must work in harmony to deliver clean, consistent fuel at the right pressure. At Diesel Pro Power, we provide a full selection of Cummins M11 fuel pump parts and accessories—trusted by more than 40,000 satisfied customers worldwide.

This section covers gaskets, couplings, fuel shutoff valves, solenoids, filters, separators, seal rings, pressure switches, and gauges—all engineered for durability and exact fit on Cummins M11 engines.

Fuel Pump Gaskets & Couplings for Cummins M11

Fuel Pump Gasket

A properly sealed fuel pump is essential to avoid leaks, pressure drops, and potential fuel contamination. The Cummins M11 fuel pump gasket ensures a tight, reliable seal between the pump and its mounting surface. Manufactured from high-quality materials, it resists wear from diesel fuel, temperature variations, and vibration.

• Designed for M11 and compatible Cummins platforms such as L10, N14, NH855, NT855, KTA19, KTA38, and KTA50.

• Prevents fuel seepage and loss of pressure at the coupling point.

• Helps maintain safe and efficient engine operation.

Fuel Pump Coupling

The fuel pump coupling connects the fuel pump drive to the engine, ensuring consistent power transfer. A worn or damaged coupling can cause misalignment, reduced pump efficiency, or premature pump wear.

• Direct-fit replacement for the M11.

• Built from precision-machined materials for long service life.

• Easy to install and critical for smooth pump operation.

Fuel Shutoff Valves for Cummins M11

12-Volt Fuel Shutoff Solenoid

The 12-volt fuel shutoff valve is designed for M11 engines in systems requiring low-voltage operation. This solenoid ensures the safe shutdown of fuel supply when the engine is turned off, protecting against run-on and unwanted fuel consumption.

• Single-pole design.

• Fast, reliable actuation.

• Ideal for marine and industrial genset applications using 12V systems.

24-Volt Fuel Shutoff Solenoid

For equipment operating on 24-volt electrical systems, the Cummins M11 24V shutoff solenoid provides the same functionality with higher voltage tolerance.

• Single-pole configuration.

• Common in heavy equipment and marine vessels with 24V standard systems.

• Delivers reliable fuel cutoff under demanding conditions.

Solenoids & Seal Rings for Cummins M11

12-Volt Solenoid (Single Pole)

Engine starting and shutdown systems depend on dependable solenoid operation. The 12V solenoid for the Cummins M11 is built for consistent power switching.

24-Volt Solenoid (Single Pole)

The 24V solenoid variant is widely used across Cummins industrial engines, including M11, N14, ISX, and QSX, offering robust switching performance for higher voltage setups.

Rectangular Seal Rings

Every fuel shutoff solenoid requires proper sealing. The rectangular seal ring ensures a leak-proof fit, preventing fuel seepage that could compromise performance.

• Two rings are required per solenoid.

• Designed for multiple Cummins engine families, including the M11.

Cummins M11 Fuel Filters & Water Separators

Standard Fuel Filters

Fuel cleanliness is critical for injection system performance. Cummins M11 fuel filters are engineered to remove impurities and deliver clean fuel under all load conditions.

• Designed with high dirt-holding capacity.

• Protects injectors and pump components.

• Maintains optimal combustion efficiency.

Fuel Filter & Water Separator Units

Water contamination is a leading cause of fuel system damage in diesel engines. A fuel water separator ensures that moisture is removed before reaching the injectors.

• Available in multiple sizes to match M11 system specifications.

• Durable housings and replaceable filter elements.

• Extends the service life of fuel pumps and injectors.

Racor Fuel & Water Separator Elements

In addition to Cummins OEM filtration, Racor replacement elements are available in micron ratings ranging from 2 micron (brown cap) to 30 micron (red cap). These are ideal for applications where ultra-fine filtration is required for marine or offshore use.

Fuel Pressure Switches for Cummins M11

Fuel and oil pressure switches provide critical feedback to operators and control systems. The Cummins M11 uses a range of make/break pressure switches to monitor conditions and trigger alarms or shutdowns when pressures fall outside safe operating ranges.

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

• Compact design with 1/8" NPT fittings.

• Essential for maintaining safe and efficient fuel system operation.

Fuel Filter Service Tools

Fuel Filter Removal Wrench

To simplify service, a fuel filter removal wrench is available for Cummins M11 filters. Designed for filter diameters between 3-7/16" and 3-3/4", this tool ensures safe, efficient filter replacement without damage.

Gauges for Monitoring Cummins M11 Fuel Systems

Monitoring fuel and oil pressure is vital for detecting issues early. Diesel Pro Power supplies a complete range of gauges compatible with Cummins M11 engines, including:

• Mechanical gauges with standard or alarm functions.

• Electrical gauges available in both 12V and 24V versions.

• Built with marine-grade durability for harsh environments.
