I bought some Jerry cans to use when towing my adventure trailer and plan on siphoning gas into my lr4 should the need ever arise however in thinking about the procedure I am wondering how to keep my siphon clean after using it without trapping fumes somewhere while storing it. I mean sure I could ziploc it I guess (are those fuel rated?) and chuck it in the enclosed trailer but I don’t want my gear to smell of gas. Anybody have a solution they like?
