yeah thanks for the reminder on that video @spikeyxxx it was the best find for close ups!
I feel like my tube sizes look good based on that video. Those totally look like half inch and 3/4 lines on the front to me. Or am I wayyyyy off base here?
I wonder if the lines in the back are larger? I’ll look into my SIS access tonight to see if I can clarify. The maintenance manual may possibly call out sizes……… wait! Oh man I have a buddy who worked at the facility near Waco that made buckets. i’ll shoot him an email today!
