I picked up an original metal Sears gas can off eBay a few years back when I began to realize the days of normal, frustration free gas cans were over. I'll have to take some pics tomorrow. Problem is, they put a plastic nozzle on it.
I'll have to weld something up sometime.
Luckily for me, one of the benefits of working in the trash business, I was able to find many normal vented plastic cans ... and on other occasions, the plastic caps & nozzles. I've got a few parts laying around to make a few good cans. I've got quite the assortment of 1, 2, 2.5, & 5 gallon cans.
Also still have my 5 gallon plastic can from 1991. Still works great. Even the yellow nozzle hasn't cracked yet! I left premix from my old 250R in there for about 4 years, then burned it all in some lawn equipment & another dirtbike I had at the time. Remember those days of good gasoline?
