Its F4 and F3 petcock compatible?
I have an F4 and broke the petcock cant find it online but i find a F3 petcock for me looks the same but im not sure if the nut will fit. Need help

 

Go to an online parts retailer and compare the part numbers. That will help in knowing if they are identical or not

 

Did it the part number change but i understand that both bikes work with fuel pump and the petcock its gravity with the fuel pump suction. There is my doubt in the pics looks like the same part but change in the part number

 

I took a look on eBay comparing the 2 different models. They do look different. But they might work interchangeably. I couldn't tell if the connecting nut was the same size though.

 

Ok thanks i will try to verify with some seller and the Vin number but any ideas are welcome
