Lloyd, I am surprised that you don't just run two 4" hoses from your
holding tank. 1 for a vent and 1 for your carburetor. That way when you
run your engine your aerobically aerating, your holding tank. All the
while burning FREE methane improving fuel efficiency.

Not to worry. Lloyd has already managed to engineer his own special
"affordable" version of the Sweetank, and has installed it on his new
holding tank.

(Aw, what the hell...)

- I have TWO 3/4" vent hoses, as Peggy recommended
- I run both vent hoses with minimal bends to outlets just under the bow,
as Peggy recommended.
- I had them use 1/2" plastic to build the tank rather than the 3/8" they
recommended, as per Peggy's recommendation
- I used $13/ft odorfree hose, as Peggy and others recommended
- All fittings are on the top of the tank, as per Peggy's (and others)
recommendations (this alone cost me an extra $100 or so)

...and so on. I spend close to $2000 on the same size holding tank a
friend put in for $700.

I also have replaced the inadequate steering system Catalina used with a
more robust system Edson recommended. I've replaced the inadequate wiring,
the incorrect fuel pump, the wrong fuel filters, all of which were done
by either Catalina itself or "the Dealer", which you seem to put in high
regard.

So what makes you think I'd design a "cheap and nasty" aeration system as
you described?
