That constantly replenishing emergency tank idea of yours is one of the best
I've seen in this group. I'm still trying to figure out how I might
implement it but space, even for just the gallon I would need, is pretty
tight in a 32 foot boat.

I think it's very long odds that that the big Shelco filter would suddenly
load up. I would have advance warning from the Racor flow stopping and it
ought to take a lot longer for the Shelco to become critical. If I had to
change out a Racor filter, I would focus on getting into a safer position.
I also have two tanks so switching to the other one as well as switching the
fuel supply to the polishing output would be part of the drill if the Racor
loaded up. I'm a sailboat as well so I usually have an alternative
propulsion source.

A friend built a day tank in his old boat. He used a small electric
fuel pump as a transfer pump to fill the tank and piped the
overflow/breather line back to his main fuel tank.

He said he usually remembered to turn the transfer pump off but if he
didn't the overflow just returned to the main tank.
