This whole subject could be easily put to bed by calling your local fuel
polisher and asking the age of boats that need polishing.
I think you'll find all the 70's and 80's need cleaning and the 90's will
need cleaning in the next few years. Anything newer and there is no
problem. Meaning that if your system is clean, it's probably good for 20
years. At least, that's the way it is in the Puget Sound area. I suppose
warmer, more humid areas could be worse.
That said, I run dual Racors mainly because they were freebies and my
neighbor polished my fuel when I installed the Racors.

This is exactly what the guy with 30+ years of experience said on Saturday.
My boat/tank is over 30 years old and doesn't have dual. I haven't and
neither did the original owner keep the tank topped off. I've never had a
bacterial contamination issue, but I would certainly like to avoid one. It
was recommended to add a dual, add a biocide, add a cetane enhancer, and try
to keep the tank topped. I think I'll take his recommendations, given his
years of experience and world-wide reputation.

No put down on anyone else intended. But, I think I'll use the Occam's Razor
approach. His advice is simple and makes sense.
