    I need to buy some 90 degree brass fitting to move the fuel lines away from the hot exhaust. But what size do i get? I see 5/16, 3/8.. or do i get 3/16 ? I DON'T KNOW WHICH ONE TO CLICK "BUY" ON ! aAAGHH! lol. These brass fittings arent exactly cheap either. I can get 2 5/16 fittings for $8 or...
