About Our Marine Fuel Filters
When uptime is paramount, DAVCO delivers 5-minute, no-hassle filter changes for reduced downtime. These components are engineered specifically for commercial vessels like push boats, ferries, shipping vessels, tugs, commercial fishing, and other workboat applications.
DAVCO offers solutions for engines up to 110-liter displacement. Our marine fuel water separators are encapsulated in a welded steel enclosure to meet the stringent requirements of the American Bureau of Shipping (ABS). The Sea Pro® Duplex system allows for changing filters while engines run, permitting continuous operation of mission-critical power, safety systems, and other technology.

- Water damage to key components – When water enters equipment, it can cause corrosion, microbial growth, and rust, which can result in severe or permanent damage to critical components. This can include pumps, engines, injectors, and more.
- Fuel filters that continuously clog – Filters that frequently clog can be the result of poor-quality diesel plugging marine fuel water separators, causing unnecessary and costly downtime. DAVCO filters feature increased surface area for maximum capacity and come in a variety of micron ratings and filter technologies.
- Lubricative coatings that are displaced – Water that seeps into your system can displace the diesel fuel’s lubricative coating on essential components, which can cause surface pitting, fuel pressure loss, tolerance erosion, and an overall decrease in performance.

“With the help of Guerry Williams and Dan Ruppel, we found an answer to our long history of fuel contamination issues. With their expert help they have helped install “DAVCO” fuel filter units on all of our new and near new trucks. The DAVCO units are capturing the contaminants that were collecting in the OEM filter housings and filters, causing engine shut down and performance problems. While we can’t control the cleanliness of the fuel dispensed in our tanks, we are now able to clean it up before it reaches the critical components in the engine fuel systems. All new trucks that come into our fleet now are being specked with appropriately sized DAVCO units if the OEM has that option.”
