Yeah. I have been doing the squeeze thing but my gas tank skid is about even with the whole. Im not getting any younger and flexibility is leaving fast lol. Last time I raised the rear of the jeep to get enough space.I have a pump that attaches to the gallon jug with a hose to get it in. Looks like the pump you see on a shampoo bottle. Other option is to buy the quart containers and just squeeze it in.
