After flying for six years, finally removed and disassembled my glass and
foam header tank. During those six years I periodically used ethanol fuel
and whatever. Always used auto fuel.  No evidence of degradation of any
component....soft aluminum, foam, epoxy. All looks perfect.
 
I'm going to replace glass tank with aluminum so I can mount two wet
pumps inside. Wet pumps the only way to go for safety advantage.
 
Just a reminder, all epoxy that is fuel exposed must be high ratio type.
Like 4 to 1.   50/50 ratio epoxies can NOT handle fuel over time.
