Both the yellow (larger) and the greenish blue (smaller) Troy-Bilt TB146 EC
cultivator gas hoses crumbled when I took it out of storage.

I bought hoses at Home Depot but how do they connect to the gas tank?

There's a black connector half way up (one way valve?) so it's easy to
connect to the carb but how do I make a watertight gas tank connection?

Is there something inside the gas tank that holds them in place?
