Fuel Pump Regulator Gasket Set for Cummins KTA19

This gasket set is designed for servicing the fuel pump regulator on Cummins KTA19, KTA38, KTA50, and QSK19 engines. The regulator controls fuel pressure to the injectors, and any leakage from worn seals or gaskets can lead to erratic performance or loss of prime.

Gasket Set Features:

• Includes all necessary gaskets and seals to reassemble the fuel pump regulator

• Made from heat- and fuel-resistant materials

• Direct fit for KTA19 and compatible engine series

• Supports marine, industrial, and generator applications

Replace these gaskets whenever the regulator housing is opened to maintain tight fuel system integrity.

Fuel Pump Gasket for Cummins KTA19

This gasket seals the interface between the fuel pump and the engine housing or drive coupling. It is a critical component in preventing fuel leakage and ensuring proper alignment.

Highlights:

• Compatible with multiple Cummins platforms including KTA19, KTA38, KTA50, L10, M11, N14, NH855, and NT855

• Designed for fuel pump couplings

• Fiber-reinforced to resist breakdown from diesel fuel and heat cycling

• Easy to install during routine fuel pump maintenance or replacement

A damaged or missing gasket can result in fuel drips, loss of suction, or performance issues, making timely replacement essential.

Fuel Filter & Water Separator for Cummins KTA19

Diesel engines like the Cummins KTA19 depend on clean, water-free fuel. Our direct-fit fuel filter and water separator offers exceptional protection by removing particulates and separating water before it reaches the injection system.

Specifications:

• Designed for heavy-duty marine and industrial service

• Built-in water separation to guard against injector damage

• High-capacity design supports long maintenance intervals

• Standard thread and housing size for easy replacement

Regular filter changes help extend injection system life and preserve fuel efficiency.

Fuel Filter Removal Wrench

This universal fuel filter removal wrench is designed to fit a wide range of filters from 3-7/16” to 3-3/4” in diameter. It provides the necessary grip and leverage to remove tight or seized filters without damaging the housing.

Tool Benefits:

• Compatible with most Cummins and Detroit Diesel fuel filter housings

• Heavy-duty construction for workshop or onboard use

• Ideal for routine maintenance or emergency service

An essential tool in every engine room or service kit.

Racor Fuel Water Separator Units

Water contamination is one of the leading causes of diesel injector damage. Racor fuel/water separator units are trusted worldwide for their proven multi-stage filtration performance. We offer complete Racor-style assemblies for marine and stationary Cummins KTA19 engine installations.

Available Models:

• 500 Series: Compact size, ideal for moderate flow rates

• 900 Series: Mid-range solution for larger fuel systems

• 1000 Series: High-capacity unit for high-demand applications

Each unit includes a filter element and is designed for easy service access and long-term reliability in saltwater environments.

Racor Fuel Filter Elements

We supply genuine-style Racor filter elements in a range of micron ratings to suit different fuel quality conditions and filtration goals. All filter elements are compatible with their respective Racor separator housings.

Filter Types by Micron Rating:

• 2 Micron (Brown Top): Maximum particle removal; ideal for ultra-clean fuel delivery

• 30 Micron (Red Top): Best for primary filtration where water or large debris may be present

Available Series:

• 2010, 2040, and 2020 series filter elements

• Compatible with Racor 500, 900, and 1000 housings

Choosing the right micron rating ensures proper staging in multi-filter setups and protects high-pressure fuel injection systems.

Zinc Anode for Fuel & Oil Coolers

Marine applications expose the Cummins KTA19 fuel and oil cooling systems to galvanic corrosion. Our zinc anodes thread into fuel or oil cooler housings and help prevent electrolytic damage in saltwater environments.

Features:

• 3/8” NPT brass plug

• Designed for marine fuel and oil cooler applications

• Easily replaceable during regular service intervals

Replace zincs periodically to protect metal surfaces inside your cooler from long-term corrosion.

Fuel & Oil Pressure Switches (5, 10, 20, 27 PSI)

These switches are designed to monitor pressure in fuel and lubrication systems. They open or close electrical circuits at preset PSI ratings, making them ideal for alarm systems, shutdown protocols, or pump controls.

Available Switch Ratings:

• 5 PSI: Early alert for fuel supply or priming issues

• 10 PSI: Typical for main pressure monitoring

• 20 PSI: Used in high-performance or dual-system setups

• 27 PSI: Useful in systems with higher-than-normal pressure requirements

Universal Features:

• 1/8” NPT threading

• Electrical “make/break” design

• Compatible with Cummins, Detroit Diesel, and Caterpillar engines

Select the switch based on the specific PSI thresholds for your fuel or lube oil system.

Mechanical & Electric Gauges

Monitoring fuel system performance is vital for Cummins KTA19 engine operators. We offer a full line of gauges to measure pressure, temperature, and more—designed for integration with marine control panels or standalone installations.

Types Available:

• Standard mechanical gauges: Direct-read for fuel or oil pressure

• Mechanical gauges with alarm contacts: Ideal for marine engine rooms

• 12-volt and 24-volt electric gauges: Compatible with both vessel and genset systems

Pair these gauges with our pressure switches for complete engine monitoring and protection.

Importance of a Reliable Fuel System on Cummins KTA19 Engines

The Cummins KTA19 engine is often deployed in high-output roles such as tugboats, offshore vessels, power generation units, and mining equipment. These operating environments demand consistent fuel delivery under a range of conditions—fuel quality, humidity, salinity, vibration, and temperature fluctuations can all affect system performance.

Common Symptoms of Fuel System Issues:

• Hard starting or loss of prime

• Excessive smoke on startup

• Irregular engine RPMs under load

• Injector misfire or surging

• Premature fuel pump wear

To maintain peak performance and uptime, it's essential to replace worn gaskets, service filters regularly, and monitor pressure with accurate sensors and gauges.
