Petcock questions

My petcock is leaking on my used bike. It seems like it is leaking from every place it possibly could be but I'm going to try to replace the O ring at the top to see if it fixes it anyhow. In the event that I do need to buy a new one is there one anyone recommends? The strange thing is that mine seems to have 2 outputs and a vacuum port but everything online seems to only have one port and a vacuum port, would this just require a fuel hose that split into two lines to reach both carbs? Including pictures for reference.

You can either do a petcock rebuild (kits on ebay for $30), buy another OEM for $60, or put in a TW200 style petcock.

I replaced mine with an OEM unit; I am not fond of the TW200 units as they do not allow as much fuel flow, but many have had success.

I had the same problem with my petcock and I finally decided to go the tw200 route except I bought cheap one on Ebay and it leaked worse than the old one. So I went to the Yamaha dealer and they sold me a new one for another bike that was identical to the tw200 for $29.00

It works great and I have no issues with not enough gas flowing thru it. I can get you the model number for it if you will pm me and I will get it for you when I get home.
