1972 20' cc seacraft fuel tank location

[real deal]

Thanks for the replies, how many gallons are these tanks ? they dont look very big
I also plan to install a under deck tank and raise the floor 2-4'' for self bailing but i want to fish her for the summer then rip her apart in the winter , that is pending on if the transom holds up for the summer, i have some small to medium cracks around stern area. Shes got an old 1988 200hp yamaha on her.
