A bunch of my Blitz 5-gallon portable gas containers have the lousy spout
broken (cracked around the center so that they now leak).

The company appears to be out of business, even though the gas cans are
only a couple of years old.

The gas cans are fine. Just the spouts are broken. I never use the spout
anyway. I just remove the spout and pour into a funnel.

Since I just use the spout as a gas cap, is there a replacement gas cap
that you know about for the 5 gallon Blitz gas cans?
