I have been helping out a friend the past few days with some things on this 300D NA. Well I discovered yesterday that he had a bad fuel leak at the tank strainer. I think its leaking at the tank but everything is wet and hard to tell. He wants to go ahead and replace the whole thing, hose, copper washer, and strainer. Pretty easy job but my question is, what size is the tank strainer nut? Thanks
