Fuel Pump Drain Hose Size?

Sean, I recall your catch can...  Thanks for your comments.

Sean, do you have a photo of your catch can?

Hi Sean,

I have a detailed article entitled "Rotax 912 Fuel Pumps" from Rotax-Owner.com dated 9/15/22.  It discusses the "catch can".  It says "Oil coming out of this line indicates a Garlock seal failure.  Fuel coming out of this line indicates a fuel diaphragm failure."  So, the question is "how much oil or fuel in the catch can indicates a problem?"
