The filter itself features a unitized mounting bracket for mounting versatility, an in-head primer pump for quick fuel system priming, a sediment and water collection bowl, and a 10 micron Aquabloc®II filter element which repels nearly 100% of all free water found in fuel. Be careful which filter you use. There are several replacement elements available that look identical. For example, there is what appears to be the same filter that only filters down to 30 microns. It leaves particles in the fuel that are too big and may clog the engine's filter. Another version filters to only 2 microns. This is filtering particles from the fuel that are so small it may clog almost immediately, leaving you without power soon after replacement.

This is an easy installation: Locate an appropriate spot on a bulkhead adjacent to your existing fuel pump to mount the filter. Install the filter on the bulkhead. Install the appropriate pipe to hose barb adapters. Cut the fuel line at the appropriate spot. Slip the two ends of the hose onto the filter, one onto the inlet and one onto the outlet. Clamp the hose to the hose barbs securely with the special clamps provided. Bleed the system, first with the hand pump on the top filter, then, on a Universal Diesel, by opening the bleed valve and energizing the electric fuel pump. You're done!

Catalina Yachts began installing similar filters in October of 1998. Boats built previous to that date would benefit from the addition of this unit as a pre-filter to remove both water and contaminants from the fuel supply. In fact, engine installation instructions from Westerbeke (who make the Universal Diesel engines), require the installation of a filter before the fuel pump.

Our kit includes:
• Filter with built in mounting bracket.
• 10 micron filter element.
• High quality, smooth ID hose camps to avoid damage to the hose.
• Pipe thread to hose barb fittings to adapt your 3/8" fuel supply hose to the filter.
• Both straight and 90 degree elbows are included to achieve the best installation with the least strain on the hose regardless of where you have to locate the filter.

Consider adding valve(s) #Z2960 pictured below under "May we also suggest" to isolate the filter from the supply line and eliminate air ingress into the lines when changing the filter.

• Height overall: 8".
• Depth (not including pipe to hose adaptor): 4".
• Port size: 1/4" NPT.
• Hose barb adapter (included with purchase): 3/8".
• Mounting holes: Two, slotted for mounting versatility, i.e. when drilling in a difficult location you may not get the holes exactly 2" apart.
• Mounting hole spacing: 2".
• Fastener size: Clearance for 5/16". We would typically use #14 screws.
