Guiding a stick to access the low part of the tank is great idea; now that you mention it, I
think I recall seeing a tank access plate which would make that idea a breeze.
I did have issues with the OPSS once before, I'll re-check that.
Thank you for the reminder about the auxiliary tank. I don't have an extra tank so hopefully I can pinpoint the issue and resolve it before I need to buy one.
