I needed this pump to empty the gas tank on my 98 4Runner. I had to drop the tank to do frame welding right next to the tank. I after pumping the fuel out, the truck only ran for about 20 seconds. I’m amazed that I was able to get ALL of the fuel out. My only word of caution, is to be mindful that there is a moving float mounted on a thin arm inside of fuel tanks. Be gentle as you insert your hose to avoid bending the arm and throwing off the gas gauge reading. I pumped it directly into another vehicle. Try THAT with a siphon.
