I have seen a few of the racks. They are scarce. Right on the tops. I have one pump. It has a top. Has a crack in it that the previous owner used silicone to fill it and so far it is solid.
I would like to know just how many of those pumps/racks were made by both companies. I had a former Mobil distributor tell me that those pumps were three times the price of a pump at the time. His company did not use the pumps because of that high price.
