I have the same thing. One gray goes out when I pull and the other has a black handle that is in front of both the black tank lever and another gray.
I am setting up for the weekend so I am lucky to have it home for a picture. Basically, gray 1 and black will not "go" if the main is not pulled. Make sense?
