My system
I'm running -3 teflon lined Aero quip line on my shurflo system but when I got up near 70% alcohol ( mix of ethanol and methanol) the pump seals took a crap and ruined the pressure switch. I got a Viton seal from shurflo but have not run it yet as it's too cold here to need WI ( 2.1 Deg F coming home from work this morning).
If you want a guina pig for high alcohol mixes, I'd be interested.
Will be warm enough to use WI in about 16 weeks.
