Well, I spent the better part of 30 minutes looking for my circular cutting tool....no luck! I was trying to cut out a piece of aluminum to fit over the vent hole in the Bay2 Fuel Tank Rib to keep fuel in the bay closest to the pickup. I realize this could make thing slower when it comes to filling the tank, although I hope the affect is minor.
I finally used some tin-snips and the belt-sander/Scotch-Brite Wheel. Good enough for the intended purpose. Will rivet in place tomorrow morning.
