Putting back together my F3 that I bought it had been taken apart by somone else and many parts lost. 3 fittings on the bottom of my gas tank, Im sure of the hose for fuel main to the petcock. But there are2 others, small one looks like a vent, the other a drain. I wanted to know if you guys could look at your bikes and let me know where they route to. I have the manual butitsto difficult to tell where the go. Also I have 2 drain tube off my carbs where exactly are they supposed toexit the frame?Thanx in advance to all, Nick.
