Review on Valterra T1003-6VP Durable Plastic Valve Handle by Fernando Beck

Replaced a missing handle on my black fuel tank valve (my old RV was like that. Had to hold the valve stem with pliers to screw it on but it holds and works well. Just buying the handle saved me money and time saved Since I did not have to change the valve myself. I have little money, so where to repair inexpensively, I do. How do I know which one to buy? I looked at the handle on the gray tank valve and adjusted, as they say, easier.
