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.

Just to clarify the letter a bit.

TiN coatings are used to impart galvanic protection on non-titanium metals. Titanium itself is the least susceptible structual metal available. On boats the only material likely to cause galvanic corrosion to titanium is carbon fiber, and in that case the titanium will take significantly less damage than 316 stainless parts.
