DIY Fuel Polisher
Your article on the Parker FPM-050 Fuel Polisher (December 2011) failed to make it clear that this “fuel polisher” is not much more than a piezoelectric pump. Granted, the FPM-050 has its niche (i.e. low power allowing for continuous running, quiet with no moving parts, and meant to be retrofit to an existing fuel filter), but you can make a dedicated fuel-polishing loop for less money.
We chose a Walbro FRB-13 pump [Editor’s Note: Be sure to use a pump that’s certified for use with fuel], Racor MA500 filter, Trident A-1 fuel hose, and a Filter Minder, which is a vacuum gauge (available from Parker) that tells you when the filter is getting clogged. Add a switch and some dedicated inlets and outlets to the fuel tank, and you’ve got a dedicated loop.
It’s important to recognize a “fuel polisher” is nothing more than a pump to move fuel, a filter to polish, and some tubing and valves to control flow. DIYers have a variety of economical ideas; just search the Internet. Commercial offerings have their place, but I’d rather spend my limited sailing dollars on useful sailing gear than on a fancy commercial fuel polisher.
