SIMPLE TO USE SIPHON PUMP WITH 6' TUBE Gas Guzzler Our bulb-type manual siphon pump comes with 12" and 45" lengths of clear vinyl 3/16" tubing that attach to a 3-1/2" long x 1-7/8" dia bulb. Made for petroleum products. At $3.50, it pays for itself with the first gallon you suck out of your neighbor&#39;s Toyota. (Just kidding!) Use it to empty oil on something besides the garage floor or your head, fill the mower straight from the mini-van, or transfer gas from one vehicle to another. (Check to make sure you own both vehicles first.)
