Polish Your Diesel Nonstop

Parker FPM-050 Fuel Polishing Module

Parker FPM-050 Fuel Polishing Module

Parker Hannifin has a remarkable new fuel polishing system that has been designed specifically to run nonstop, using extremely small amounts of electricity and with a design that makes it seem nearly immortal when compared to conventional pumps.

The new FPM-050 Fuel Polishing Module (click on the photo above for a larger view) consists of a state-of-the-art piezoelectric pump that uses about 2 watts to run, equivalent to 3.6 Ah/day. With such a low power draw, Parker says the unit can run continuously and unattended for extended periods of time without depleting available batteries. The system is designed to remove emulsified water from diesel fuel systems. It will filter 50 gallons of fuel a day — which at first glance seems like a fairly small quantity. But imagine how long your boat sits at the dock, between weekend cruises, or even during the off-season. In less than three weeks, it will run a typical cruiser’s 1,000 gallons of fuel through the Racor filter in the system. If installed on a new build, or after a comprehensive system and fuel tank cleaning, it should enable that system to remain pristine and free of water problems.

Parker says the design of the FPM-50’s pump eliminates many of the wear points that others typically have, “enabling owners of the FPM-050 to enjoy many years of use without seeing performance diminish over time.”  The product brochure — which you can download here — shows typical installation diagrams, both for use inline with an existing fuel system, or as a dedicated fuel polishing loop.

An available timer accessory can help you run the system on a regular schedule.  My only question about the system has to do with the advisability of running a fuel pump of any kind while the boat is unattended. I have contacted Parker and am awaiting an answer on that issue. Maybe readers have an opinion or experience with unattended fuel polishing?

Price for the full FPM-050 installation kit, including the unit and a Racor 503MA-10 filter and FPM-PTC-12-A Timer is $1,149.
