RE: Is my tank upside down?
Its seldom a problem and certainly not as big a problem as the rediculous practice of hard mounting and glueing a tank to the firewall and then turning aroundand padding the rest of the tank with foam? thats absurd. Or now this gentlemen who probably will end up destroying his tank getting the thing out.
If a simple hole bothers one just make the thing smaller with a bit of balsa or something.
