There is no simple access point near the gas tank when draining the gas from a VW Bug, also known as a Beetle. Instead, drain it from the fuel line under the car, near the left rear wheel. Any other location on the fuel line is either too high to drain the tank effectively, or it is hidden behind metal sheeting. The fuel capacity of most VW Beetles is 10.5 gallons, so make sure you have enough gas cans to catch all the fuel.
Loosen the lugs on the left rear wheel. Jack up the left side of the VW Bug. Remove the lugs and the left rear wheel.
Locate a hose clamp under the car, just inside the left rear wheel and a few inches in front of the axle. (This clamp connects a flexible fuel line running from the front of the car to a metal fuel line running up toward the rear and to the fuel pump.)
Place an empty gas can or bucket under the car, as close to the flexible hose as possible. Loosen the hose clamp with a nut driver. Slide the loosened hose clamp toward the front of the car.
Slide the flexible fuel line off of the metal fuel line with your fingers, taking care not to spill fuel. Quickly place the end of the flexible fuel line into the bucket or one of the empty gas cans.
When the tank is empty, slide the flexible fuel line back onto the metal fuel line. Slide the hose clamp back into position, and tighten with the nut driver. Remove the gas cans. Clean up any spills with a rag.
Replace the wheel and lugs. Tighten the lugs. Lower the car.
