Partzilla shows a part number of 44300-12F00. The one you show would probably work too.

Have you considered just getting the repair kit for the petcock? It would save you some coin and they are pretty easy to replace.

Also, be sure to check the vacuum hose on the back of the petcock that goes to the carb. If it is cracked or loose, you would get the same result.

Good luck.
