Stuck at Wrecked Ship in Super Metroid

In light of Metroid Dread's recent release, I've been doing my best to play all the mainline Metroid series games. I'm currently on my playthrough of Super Metroid, and am stuck at Wrecked Ship. I have been trying, and failing to find the reserve tank. can anyone tell me how to get to it, or just give me a general idea of where it is?
