Hi does anyone know what the diameter of the crank breather tube is on an 01 426? Im Looking to do the filter mod, and found a uni crank filter for a
3/8" breather hose. Could this possibly fit on the stock tube? I was going to use one from autozone like I had seen in a post here, but the filter was huge and it looks like it could get in the way. Thanks

3/8 will never work. I'd say 1/2" without measuring (which you could do).
