I am a big fan of Cleveland Tools, but I had their red fuel valve and did not like it. I didn't like it because of the way it works...it has a round hole for mounting and it has an allen screw that presses against the flat spot on the valve "shaft". Yes I had the allen screw installed with loctite and it never failed on me and it was still tight when I removed it, but it made me nervous every time I turned it.
I then installed the Van's lever (part #: FUEL VALVE LEVER) and it has the hole machined in the same shape as the shaft so there's really nothing to fail. The Van's lever is also a bit larger which I like (it's also more ergonomic).
I simply don't like adding one more failure mode (a screw backing out) to my fuel system.
