How to Siphon Gas From One Car to Another
- 1). Move both cars alongside one another in a manner that puts both fuel filler necks within several feet of one another.
- 2). Remove the fuel caps on both cars.
- 3). Slide the inlet hose on the automotive fluid pump down the filler neck of the car with the gasoline. Push the outlet hose down the filler neck of the car you want to fill with gasoline. You can purchase a pump at your local auto parts store.
- 4). Follow the fluid pump's specific instructions to pump the gasoline from one car to the next. This usually entails holding the body of the pump firmly with one hand while you move or pump the handle up and down to draw the gasoline up the inlet hose and force it down the outlet hose.
- 5). Continue pumping until you have siphoned the desired amount of gasoline and then remove both hoses from both cars and reinstall both fuel caps.
