[The parts I replaced with ethanol resistant ones were]
#1 - the flexible hose that connects the metal fuel line to the mechanical fuel pump,
#2 - the mechanical fuel pump diaphragm,
#3 - my Holley Model 94 carburetor accelerator pump.

Even with these upgrades I have used nothing but pure gasoline... so here is my question. Are my upgrades sufficient for the use of ethanol and pros and cons of ethanol use over pure?

Thanks all!
#4 - tank to firewall fuel line (rust-out)
#5 - fiber fuel pump valves (sticky)
#6 - fiber carb needle valves (sticky)
#7 - 4 oz of Stabyl Marine in every tank (puts a layer of oil atop the fuel to prevent absorption of moisture)
