I had something similar: stupid person in a parking lot damn near rammed me as they were backing out without looking; I swerved right, mounted a curb, and broke the drain side of my grey tank. The tanks are ABS, you get get ABS cement and solvent at any good hardware/home repair store. The actual dump valve you should be able to order online, e.g., Amazon. I'm thinking you don't have enough pipe left to connect a gate valve to, so I'd cut the elbow off leaving an inch or two on the tank, get another ABS elbow and a short section of ABS pipe, dry-fit everything, then clean with ABS cleaner, put on the ABS cement and connect (one joint at a time), then put the gate valve and cap on.
