Project Farm: Ethanol vs Non-Ethanol fuel test

After rebuilding a couple of Nikki carbs in Briggs engines and having to replace various rubber o-rings and gaskets that failed from what is likely ethanol exposure I have switched to ethanol free in all of my equipment. As of right now it is $3.89 a gallon. I did a comparison of running e10 with ethanol shield and running e0 and it was less than 50 cents per gallon difference. I consider this to be negligible so why deal with having to mix in additives. I also keep 10-15 gallons of e0 on hand at all times and rotate the gas every 6 months regardless so I should never have a supply issue within my own garage.

Back around 2008, while doing maintenance on the boat engine, cowl off, I spotted something in the under cowl fuel filter.

Seems the Marine fuel line, INTERNALLY, broke down and turned to what appeared to be slimy spaghetti. This was in-between the primer valve and engine filter.

Thank you Ethanol...






Knock on wood I found it at the dock and NOT miles from land, stranded...

Common fuel lines on weed eaters brought in for repair, again, thanks ethanol:
