I received the two Mini-kegs from Midwest Supplies. There are about 9 3/4" end to end and 6 1/2" in diameter.
Think I will use them as long trip tanks and make a V8 Tank for shorter trips.
I need to test the rubber in the bungs to see if they swell wt. gas? I didn't expect the 2nd bung for the outlet at the bottom. The top bung comes with a plastic plug to just keep junk out. The top bungs had to be ordered separately. If the rubber isn't compatible, guess I will have to solder SS plates over them.
