I will demonstrate the problem using a large O-ring from the bottom plate of a 1960s Mercedes Fuel Injected Electric Fuel Pump.

Excellent demonstation Kent. As usual, you present logically, analytically, and simply.

The damage to seals and rubber is crazy with modern fuel, many thanks Ken for video.

In the UK we can still get fuel that is 1-2% ethanol but it’s getting harder and harder to find

I wonder if Esso 99 octane really is ethanol free?

Hey Kent, sent an inquiry through your merchandise website and followed it up with two emails, but haven't heard anything back. We were interested in purchasing but is not clear as to which is the correct package for our car. Thanks

Ethanol is bad stuff on all fuel systems

Not in modern cars fuel systems, these are built from factory for ethanol blended gasoline.
