Last summer trip, we smelled gas leaking, and then heard the hissing. Oh no! So now time to replace this. Probably is the original one from 1985. (yes, the tank is probably too! , that is getting replaced too, don't worry ) But since I don't know what type this is exactly, I am asking for help. What do I need to get exactly? Maybe someone could send an Amazon link. OR is it best to get locally at a store (we live in Los Angeles, so not always easy to drive in traffic all over looking for correct part in stock) Let me know what I need please. Oh, don't have heater at all, just 1 stove, and frig (tho ol' frig hasn't worked in a while) mainly for cooking stove. thanks!
