I never turn my fuel off in my 812, there's no reason for it. When on a
hill or refueling and I'm trying to get as much gas in as possible I
will turn it to R or L. It does not matter which one.

I have proven empirically that keeping the tank switched to L or R helps. Both
the local ramp by the fuel pumps and my tiedown are on slopes. If I fill the
tanks to 1.5" below the filler tube (which is normally safe), park on my
tiedown, and leave the selector in the "off" position, the right tank (the
uphill one) will be down about 1/4 tank a week later. Leave the selector on R,
and I'll still have full tanks. Similarly, if I leave the selector "off" while
I'm fueling, frequently the downhill tank will overflow before I finish paying
for the gas. I have developed the habit of leaving the selector on the uphill
tank, but I cannot give you a good reason for doing that instead of the downhill
one.

And no, I'm not aware of a fix. Seems to me that Maule would offer that as an
option if there were one.
