Hi Gary,
I also have the smaller tanks (but they are actually 8 gallons, not
7.5). I fill them to about 1" below the filler hole.

I have the 46 coupe 415-C. I also have the 7.5 gal tanks, instead of
9 like most of you do. My question is, how full to fill the tanks. I
have heard that up to the brim, and I will lose fuel to siphoning. I
never had this problem in my 172, and I wonder why the coupe tends
to lose fuel this way. I am now putting too little fuel in, and just
want to know a good ballpark average the rest of you men/women use.
Thanks for reading this.
Gary
