For what it is worth fuel tanks are measured in fluid ozs. ie- sixteen fluid oz. of fuel may not actually weigh sixteen ozs. on the scale. For example fill your 16.oz. tank with water and then fill it with liquid mercury and the weight of the two will be vastly different.

I have a quick question for Kevin. In Jeff's forum you stated that your Simla came in at 8.43 lbs. Was that flying weight, dry weight, or something else? I have weighed everything except the wing including the radio, engine, etc. and I am at 6.91 lbs before any finish work. I am estimating 9.5 to 10.0 lbs by the time all is said and done. I am hoping that I can reduce that some. Only time will tell I suppose.
That is all up finished dry weight. Add 16oz or 1 pound to that once I fuel the tank to capacity. I did not try to make it lighter with any sort of holes or boring. I built the plane as simple as possible. The only thing I did to get rid of much excess weight was sanding and more sanding. The only thing that I did not almost sand through was the rudder and I wanted it fat. I weighed it before I started final sanding and carving block. At pre-sanding/carving it was at 10 pounds all up weight. Attached is a picture of my scales at weigh in. I just noticed that I need to correct the weight of 8.43 to 8.36 pounds. Sorry guys my mistake.
