4120 Diesel Spin-On Series Element, Replacement Element - 10 Mic

The Racor 4120 Diesel Spin-On Series is a crucial component in marine engine maintenance, offering superior fuel filtration for boaters. This series, which includes models R120S, R120T, and R120P, provides effective protection against fuel contaminants, ensuring optimal engine performance and longevity. Fits Fuel Assembly Model Numbers 4120R/6120R

The 4120 series is designed with several notable features:

• Efficient Filtration: These filters utilize Racor's high-efficiency Aquabloc® engineered media, which effectively repels water and removes solid contaminants from fuel at 98% efficiency of their micron rating.
• Versatile Options: Available in different micron ratings (30, 10, and 2 micron), allowing boaters to choose the ideal filtration level for their specific needs.
• Easy Maintenance: The spin-on design simplifies service procedures, featuring a reusable clear plastic or metal contaminant collection bowl with a self-venting drain.
• Corrosion Resistance: The mounting head and filter body are protected with a durable electrostatically-applied powder coating.
• Optional Features: Some models include an integral priming pump for easy priming and simplified service, eliminating messy filter pre-filling and engine hard starting.

Importance of Proper Fuel Filtration

For boaters, maintaining clean fuel is paramount. Even small amounts of contaminants can cause significant damage to modern diesel engines, which often inject fuel at pressures exceeding 36,000 psi. The Racor 4120 series plays a vital role in:

• Removing water, which can lead to bacterial growth and corrosion
• Filtering out particles like sand, dirt, and rust
• Extending the life of injectors and other fuel system components
• Ensuring consistent engine performance and fuel efficiency

Choosing the Right Filter

When selecting a Racor 4120 series filter (R120S, R120T, or R120P), consider:

• Flow Rate: Ensure the filter can handle your engine's fuel flow requirements.
• Micron Rating: Choose based on your specific filtration needs and engine manufacturer recommendations.
• Bowl Material: Opt for clear plastic for easy visual inspection or metal for high-heat locations.

Maintenance Tips

To maximize the effectiveness of your Racor 4120 series filter:

• Regularly inspect the filter for signs of contamination
• Replace the filter element when the vacuum gauge reaches about 5 inches of Hg or annually, whichever comes first
• Drain water from the collection bowl as needed
• Follow manufacturer guidelines for installation and replacement

By properly maintaining your Racor 4120 series filter, you can significantly reduce the risk of engine problems and ensure smoother, more reliable operation of your boat.

FAQs

Can I use a 2-micron filter element in my primary filter?
It's generally recommended to use 10 or 30-micron elements for primary filtration, reserving 2-micron elements for secondary filtration to prevent premature clogging.

Is the Racor 4120 series suitable for gasoline engines?
While primarily designed for diesel applications, some models can be used with gasoline. However, specific precautions must be taken, such as using metal bowls in enclosed locations and avoiding the use of heaters or water probes.
