Stus-List Re: Accurate Fuel Tank Measurements
Got it. Calibrating the gauge can be done albeit crudely by starting with an empty tank and adding x-gallons y-times until the tank is full WHILE simultaneously noting/marking the fuel gauge ‘face’ as you go. Pretty crude and slow and with the small size of most fuel gauges not very precise. The bigger the fuel gauge face (diameter) the better! My gauge is say 2 inches in diameter and uses say the upper part of it with say 180 degree arc (likely less than 180 but let’s keep it simple). If the tank was level and cubic, easy peasy since 1/4 tank would be at 1/4 of 180 or about 45 degrees, etc with 1/2 showing 90 degrees, etc. (This is the default ‘calibration’ of most resistance based senders.) If odd shaped, not so much! Further before you begin you must fill the tank or otherwise know it’s capacity. Then you fill tank to 1/4 of capacity and mark gauge, 1/2 capacity and mark gauge, etc. By the time you finish this, you will have a crudely calibrated gauge—I say crudely since the width of your marks on the gauge face correspond to probably +/- a gallon or more as the gauge gets smaller and/or your marks get bigger. In the end, your calibration approximates the actual fuel volume in the tank as long as you read your gauge marks consistently. After I went thru this on my boat, it was so crude that I don’t use it—I just ALWAYS carry an extra 2 gal diesel supply in my lazarette. This is enough to get me to any marina in my area of sailing on the NC sounds if I run out of fuel. I also keep a record of my fuel fills by date and amount so that I have a good idea that my tank is almost always at least 1/2 full.

Stus-List Re: Accurate Fuel Tank Measurements
My fuel gage never worked. Last year the 42-yr-old aluminum tank sprung a leak. Replaced with plastic tank that is translucent. No need for a gage any more. Just look at the tank. 100% accurate. If your aluminum tank is 40-yrs-old, maybe preemptively replace it? It will leak eventually and it's a mess. Also curious about rationale for keeping tank full. You are in a warmish location so condensation would seem to be minimal. Are you concerned about never having a fresh tank of fuel, constantly mixing a little fresh with the old?
