I used it with a boat there was not enough tubing to get into the tank from the gas cap, hooked to the fuel line but there is a check valve, so had to take apart the gas tank sending unit and shove the pickup directly in the fuel tank. had to move the unit into a new position to have enough hose to get to the back of the tank, hard to tell if we got it all. It pumped as advertised, a nice steady flow filling up the tanks, I'm not sure how easy it would be to get to the bottom of a automobile gas tank with the supplies provided there is not an overabundance of tubing and it is coiled, this would work especially good where there is easier access to the gas tank like a snowmobile or ATV etc. I don't know how I would have done the job with out it.
