Adding third tank

[team supra]

Own a 21 cougar that has two saddle tanks now, problem is I'm always out of gas, I wish to install a third tank in rear between stringers, how do you get them to all drain simultaneously? Seems keeping fuel lines same length could be it?

how big tanks now ?

I would have the two side tanks flow into the new tank. Draw your fuel from the new one.

Two 12 gallon tanks not enough the idea of running both tanks int new one may work thanks

12 is small the 23 Daytona has 30 gal per side

My CeeBee Avanger has 2 x 20 gal saddle tanks with equal length lines "Y'd" together, and they draw pretty evenly. But with a middle tank at a different height you may have to have the 2 saddle tanks drain into the middle tank, and then to the engine. If they all draw at the same height, it may be OK.
