Orginal Gas Tank or??

[swalton12]

I have a 74 23 SF that I got last fall. The previous owner has informed me that the gas tank had been replaced and it was in their family since it was new. Upon inspection though it appears to be original or "well aged". Unlike the other posts here it only has one marking that I can find. It is a sticker that says AAAA Tanks, Inc Miami, FL. This leads me to belive it could be orginal because the boat was built in florida, but was owned and operated in South Jersey for most of her life. I am trying to make sure it is 100 gallons to ensure I have enough fuel for an upcoming trip. Anyway to tell other than running it out of fuel completely? How about the age?? Any help would be greatly appreciated!

ive done this before. its not very advanced, but it works like a charm:
1. get access to your fuel tank from above.
2. use some sort of measuring stick to see how much (in inches) gas you have.
3. fill tank to capacity, remember amount you put in. recheck amount (in inches) you have in tank now. using basic algebra you will know how much fuel you hold.

EXAMPLE- if you had 2" of gas, then added 20 gallons of gas and now have 6" of gas, you have a 30 gallon tank.

tank capacity - do it like this

length x height x width - in inches that gives you cubic inches - divide that number by 231 - that will give you your answer - take 10%,off that number for usable capacity - example 100g tank,approx 90g usable

a gallon of liquid consumes 231 cubic inches
