Hi guys,

I have a slimline pitts style muffler for a Saito 180. There are two tapped holes. One which is protruding out, I assume is the for the tank vent nipple. The other one is on the side of the muffler intake.

My first question is what size fuel line nipple do I need as the muffler didn't come with it?

My second question is, what is the second tapped hole for? Is it for the breather nipple?

Thanks
