Tried searching many forums but couldn't really find anything on mobile. Looking to buy a k&n crankcase breather filter and need exact sizing. I believe the valve cover hole size is 5/8 in and need a filter with a nipple of 1.00 in diameter correct ? SIDE NOTE: I accidentally ordered a 2 in diameter fitting a 1in outlet thinking that the 1 in would have been the diameter on the filter. Will this work since the clamps are adjustable or would it be too loose ? Thanks in advance !
