The eleven gallon ones will spew fuel out of the tube that allows atmosphere into the can if you turn it upright after a fill. I'm just happy I had the rear wheel on before I got drenched, and I was just as happy the Milwaukee Mile had a shower in the infield.
eep!
we don't have an oversized tank so it doesn't hold more than 4, no spewing fuel with that one. thankfully. since that's my job.
