What size hoses/fittings are you using? Bigger diameter hose (Gordon used 5/8" on his) will add volume, slow airspeed down and make the breather way more effective.

I posted it somewhere else, Al, but I can’t seem to find it. IIRC, it’s about a foot of 1/2” or 5/8” coming from the fuel pump block-off plate and 1/2” or 7/16” coming from the oil filler neck. (Judging from the pics above, I’m guessing it’s the smaller two. The 1/2 barb fitting came with the van and the 7/16” one I sourced at Ace.

Yes, it does add volume to the breather, but with the size of my catch-can I don’t know if it makes much of a different.

FWIW, in the three years since I installed it, I have yet to see any oil on the sight glass, so I’m happy about that.

ps: Al, sorry I didn’t see this. Just realized your post was from back in 2019.
