Blue aeroquip hose

[wirenut]

Has anyone experienced any problem with this hose when it gets old (12 years)? Not leaking but maybe deteriorating inside or coming apart inside. Mine is being used for Methanol. I'm trying to track down what has become a intermitent problem

I'd Look into PTFE hose. Teflon lined stuff.

Fuel seems to be killing most of the rubber used in any of the std approved hoses.
