A vacuum gauge is one of the best cost/benefit ratio improvements you
can do. You can save a lot of $$$ in unneeded filter changes and get
advanced warning when you do need to change one.

Time and again I have read that Yanmar does not recommend a 2/3 micron
primary filter. I therefore use a 10 micron, and use Biobar, as well
as some Seafoam. I have some old crud in my tank, but where I can
see it through the hole for the sender, the bits I can see are pretty
well stuck to the bottom of the tank (and there are not many of
them). That said, the boat had sat at the dock for +/- 6 years before
I got her, and we have run 150 gallons or so of fuel through the boat
in the last 4 years.
I change my Racor every year, and I used to change the one on the
engine every year as well. This time, I'm going to let the engine
mounted one go another year. We still get a fine layer of black
"grit" at the bottom of the racor over the year, but it does not
appear to hinder the running of the engine.
I'd rather swap out a $20 filter once a year than risk the engine
shutting down as I go through a bridge opening with 3 kts. of current.
To each their own,
Bruce
