A friend tried to sell me on one of these to no avail. They remind me of those ear candles sold in the flea market. A good, drainable Racor with a stainless mount will provide all the gas fuel polishing you will ever need in a lifetime of boating if regularly maintained. I would also be against creating a more complicated fuel delivery system on a presumption fuel quality is substandard or beyond the capabilities of what a good Racor marine filter will accomplish. Keep tanks full of non-ethanol fuel, use quality fuel stabilizers, and check/maintain you primary filter regularly.
Diesel on the other hand can be subject to algae growth and other contaminant ingress that can require more vigilant efforts if stored long periods.
