THanks.
Don't give up. It's still as good as you hoped, just go to the gas station when they're open, or be the first one after they close. You got 80psi the first time, no reason you can't get that or more in the future.
However there may be worse news. The tank starting pressure is he most you can get out of it. However you can't even get that. If you use it only for topping off tires you may do OK, but if you fill tire, each tire will drop the pressure according to the ratio between the tire and tank volume. For example if you start wih 80psi, and fill a tire that uses 1/4 of the air, you'll end up with 60psi in both the tank and tire. The next tire will drop the pessure by the same 25% leaving you with 45psi. and so on.
