The Latest Progress in Maintaining your Diesel Fuel.

No more dockside fuel polishing costing hundreds of dollars. Polish your fuel, all the time, every tank full, every day.

Go2marine works hard to keep your hard working engines running smoothly. The FPM-50 is the latest addition in list of products that help control, filter, kill or trap the bacteria that lives in the water moisture found in diesel fuel…

The FPM-50 Fuel Polishing Module  is a small, 12v diesel fuel polisher that runs on minimal electricity requirements, 24 hours a day; Consuming less than 2 watts while polishing 50 gallons of fuel, every day.

The Issue

The daily buildup of condensation in a diesel fuel system can lead to fuel contamination through bacteria growth. Parker’s new patent pending Fuel Polishing Module (FPM-050) combats the daily accumulation of water in diesel fuel systems, preventing corrosion and other system problems. Parker’s FPM-050 is optimized to remove emulsified water from the fuel system, preventing common fuel issues and maximizing the effectiveness of current filters.

How it Works

As diesel fuel warms through engine use or the daily heat of the sun, its natural capacity to absorb water increases, dissolving and dispersing a percentage of any water in the tank. When the fuel cools, this dissolved water desorbs into a bacteria-harboring emulsified suspension. By flowing the fuel gently over many hours, the FPM-050 maximizes your filter’s ability to separate this difficult-to-remove emulsion and filter out particulate.


The compact and lightweight design of the FPM-050 makes installation into the fuel system easy. The included mounting bracket secures the unit in place using standard screws. Fuel connections to the module are made using standard sized NPTF-type threaded ports, which are easily connected to fuel lines by standard crimp-on or barbed fittings.

The design also incorporates an automatic full-flow bypass valve. The auto bypass valve means there’s no need to use a manual valve to switch between polishing your fuel and using your engine.

Parker designed the system to meet the requirements of the American Boat and Yacht Council (ABYC) standards pertaining to diesel fuel systems (H-33) and onboard electronics (E-11).
