Not all technology that is cool has to be high tech. If you have ever spilled gasoline all over your expensive (even relatively speaking) motorcycle because of arguing with the gas nozzle… there is apparently an answer!
I don’t have one yet… but I’m sure getting one! The technology here is defeating the vapor recovery boot. This is also a safety on the pump to prevent accidental spills. For anything that doesn’t have a filler pipe, this boot is inconvenient (saying that politely).
The McCuff “defeats” the boot and also acts a little as a funnel. Very nice.
