I'm thinking of adding one after running out of gas 50 yards from our gate in the country. Naturally the guage is dead (another issue to solve) but I don't want to deal with this again. So, first of all, I have an old can from my youth in the the 70's that is the old WWII metal style with spin off metal lid, except it's red and at one point I think I must have replaced the nozzle because it's the smaller style that fits the new unleaded holes. But it pours painfully slow. Before I try cleaning it up and painting it, are the older large nozzles still available? Are the older style cans available still?
