408 stroker fuel requirement?

It’s an utter PITA, but if you’re really nervous about the ethanol. Buy a 5 gallon pail of the cheapest non ethanol race fuel you can get. Pull the inlet line off the pump and stick it in the pail. Run it a couple of mins and shut it off. Do this every time it is going to sit for a bit. I never cared. Never had an issue. Same needle seats 10 years old. 1/2 was pump gas use.
