lol, no the cans have just acumulated over the years. Nice to have, I have to change the fuel pump in the old ladies jeep in the morning and that means draining a full tank of gas. To make the cover I took the back cover of an old phone book cut it down taped it over the hole then trimmed it. Then I had a templet. Then I picked up some 22gauge steel from the hardware store and used the templet to trace the pattern on the steel. Then I cut it out, shaped it, drilled 4 holes in it, and mounted it.
