I recently purchased a MC100 Fuel Tool and was curious if anyone here knows much about whether it's a Good Tool or a piece of Crap tool?

 

If I had to stop and disconnect my fuel line to hook up and transfer gas out of my tank into another guy's scooter who for whatever reason can't keep his head cut-in about how much gas he has onboard, you can bet he's gonna' be buying me all the barley pops for the entire rest of the ride and maybe then some! I'd say that tool is just that, a tool.

 

Are you planning on using this regularly? If so, what would be your application?

While that tool is easy and convenient, if it's just for emergencies, you can transfer fuel from your tank through the same outlet into a cup/jar/bottle without it.
