MWC's can still be had new for $20-25, but that price doesnt make it worth the risk of using for fuel imo. Spend the extra $$$ and get a purpose built fuel container. A MFC intended for diesel can be converted to gasoline use with a simple gasket swap. There are some fairly extensive threads on thr subject here on ExPo that highlight the concerns mentioned already as well as ithers such as the thickness, markings, and the internal venting present on the MFC. Pouring fuel out of a MWC through a spout sans vent is going to be a messy or slow process, defeating the purpose of having a quality can.
