These shaker hoses need no batteries and will empty out a 5 gallon can in about 3 minutes. Just set the can on the bed rail and shake the line, it auto primes and siphons. Have one in each garage and the pickup.
put one of the caps on a 2 gallon Wedco can and sat it on its nose so it had full pressure on it. Five hours, not a drop leaked.
