For the one you linked you'll need an adapter plate kit & the tank bung hole will have to be reamed about ~2-4mm. Also, not sure, but you'll have to check the carb top clearance.

Hmm didn't think about the clearance issue well I'll take some measurements and contimplate if I want to do the work hahahaha thanks for the help as always

The fuel line is 5/16 on the 82 gpz. Have fun with anything smaller.

I just had to take my peacock out tonight because I switched tanks. Mine is almost identical to the DCC one you linked to. Apparently the PO had changed it at some point so I already have the adapter plate that Martin spoke of. Also as he said you will have to open the hole in your tank just a bit to get the screen filter into the opening. I just used a drill and run the bit on the side of the opening until it fit in the hole. I have plenty of clearance between it and my carb but I don't know if our motors differ that much.

yeah i installed mine as well works perfect i used a step drill bit (which was probably way more difficult than your approach) and its awesome but damn that sucker is heavy hahah
