Default 1970 seacraft potter

first time boat owner. I just purchased a 1970 secraft potter with a 1985 johnson. The hull is solid and the engine runs good. The question i have is my fuel tanks doesn't have a fuel sender on it so i dont know how i am suppose to mointor the use of my fuel. Anyone out there have a way of doing this?
thanks

Get a bottle of water with a ratio (relative to size of gas tank) of 10:1. Drink the water as fast as you are traveling and think the boat is "drinking" (i.e. burning fuel). The faster you go, the faster you must drink. When the bottle is almost done, you're tank is probably almost empty. That's the most accurate way of doing it.

You could also buy a new sender and replace it and the wires. It's VERY easy. I did mine. Just search around for some info.

you can add one . . . easy enough . . . or you could fill the tank and monitor usage with a floscan. For the first few trips leave margin for error until you are comfortable with accuracy or bring a 6 gallon jug. Is your tank in the console? or under the floor?

Fill the tank and spend the day enjoying your new boat.
Next trip fill your tank and spend the day enjoying your new boat.

Now you have a baseline to calculate fuel usage!

I know about the site, having issues with a virus on that site. I belive its the orignial tank. its above the deck and under the console. I have looked for the sender and dont see one. it has the original gauges on the console without a fuel gauge. ;?

In '69 and '70 the fill was on the top of the console. It connects to the fill hose and goes straight down into the tank so all you have to do is unscrew the fill cap and stick a narrow rod into the tank, pull it out and read the level. Like a dipstick. If this is what you have consider yourself lucky. It's the most reliable fuel gauge ever made!
