Even in my Jeeping days I always just used cheapo red plastic jugs for fuel
. They were a pain but they worked. The biggest problems I had were a little yellow air valve that didn't like to pop closed and one nozzle that always wanted to cross thread. It has been YEARS since I bought gas cans.
I was at Walmart before I brought the boat down from Pittsburg and it appears all the jugs now have this new design with a flow/stop lever and no seperate valve. I was disappointed because there is this large structure that sticks off the cans and I thougth this would make storage
a pain (it does) but they were only 10 bucks so I bought them.
What I've discovered is that if the can is say- a couple inches too far to each on the deck- and it has fuel
in it- if you try to drag it over by the nozzle structure it snaps off this thin piece of plastic and they no longer seal or pour. This is far too fragile for any field application.
