You need to raise the antifreeze container (gallon jug) higher than where the hose is connected to the port in your convenience center. It won't work at all if the container is sitting on the ground. I set mine on a 6 foot step ladder. I fit a bucket with a clamp on one step and put the gallon jug inside that so it won't tip over when the jug nears empty from the weight of the hose. But, that is the easiest solution. Simply raise the gallon jug a bit higher than where the hose connects to the trailer. I will probably work just fine then.
