You've found about as interesting a gas gauge as possible but because of the other disconnected elements in your shot, the overall composition suffers. Each of the other elemement (tree, pipe, branches, blue wall, red slanted thing, sky) has the same treatment as the gauge (dof, lighting, weight in the frame) so each competes to be the main subject. If physically moving about to change the frame's contents, adjusting the dof, zooming in, etc. aren't possible then another gauge would be best. I also found the crank/handle's position distracting as it covered the dial - a 3:00 or 9:00 position might have worked better -- unless that would cause gas to come hissing out :)
The gauge itself has some great color and the lock and handle are interesting elements.
If you have any questions on my comments, feel free to pm me.
The pump here (I think that's what it is!) is fighting for attention, but being beaten down by all the other stuff in the image. The light in the upper left is very distracting.
