Petcock leaking

Didn't get a chance to research this yet, but did anyone have the petcock leak from behind the shut off valve. If you look behind it there are 4 screws behind that which hold a plate? It's leaking out in between those plates. Is there an o-ring or gasket for that? I'll have to look it up when I get home.

This is where it's leaking out. Right between this plate.

Isn't that where the diaphragm is? I just purchased a new fuel petcock off of amazon and it should arrive tomorrow. I decided to replace mine when I noticed that the vacuum hose that controls it was cracked down the side and no longer connected. It was still allowing fuel to flow so I figured it must be bad; it was also causing a vacuum leak. I'm actually surprised it wasn't flooding the carbs while the bike wasn't running.

I bought mine from Amazon for $10 shipped, based upon another thread I found on the forum. It's a Yamahaw TW200. I'll let you know how works after I install it. I would post links to the store page and referenced thread, but I can't yet because I'm a noob and the forum rules won't allow me to post hyperlinks until I've made 5 posts If you want the links maybe I can PM them to you.

Yup, took out apart and ordered a diaphragm.
