The current issue of Motor Boating has it's ten tips for improving fuel
economy. The first is to install a fuel flow meter. I have one, but have
not yet installed it.

Anyway, the tips are at:

or: http://tinyurl.com/ol3sz

The tip on carrying only the fuel needed, plus a safety margin, is not one
I have been practicing. For some reason I've always thought a full tank is
a happy tank, with less condensation, etc, but this article suggests
treating the fuel with a drying additive. It doesn't go into detail about
how much or when.

Does anyone here use drying additives? How often and how much do you use?

I know nothing about them. Can you give me a link?

No. But, I got over eight million hits when I tried vacuum gauge. I was
hoping maybe you could narrow it down some. But, that's OK.

Snippy little bugger, isn't he?

You're a good man, JR!

Who makes your vacuum gauge?

Not sure without getting up and crawling under the tarp with a
flashlight. Picked it up at an auto parts store...$10 I think. or maybe
JC Whitney (.com).You have to run a 1/8" ID vinyl hose from the guage to
a manifold vac source on the engine.
