A friend of mine emailed me photos of a mysterious toy, hoping I could identify it:

I couldn’t, but with a few well-placed inquiries to my usual sources, it was ID’ed by Greg the Bunny of the RTM forum as the Star Wars “Vehicle Maintenance Energizer” from the old 1980s Kenner line.

It’s a glorified gas pump. This was definitely one of those consolation toys your parents bought you when the store was sold out of speeder bikes and Jabba playsets.
