Additional info from that same source:
Siphon instructions: Stick hose down into gas tank. Newer cars have an additional valve inside that is to prevent gas from leaking during a rollover. Supposedly a hose won’t be able to bypass this valve. You may try a small tube inside the hose (say 1/4 inch), best if the small tube is cut on an angle at the end, giving it a sharp point to try and slip past the ball-like rollover valve.
A cheap “primer pump” (rubber ball that you squeeze) can save you from sucking on the tube.
If you cannot get into the tank that way, you can try to get under the tank and get into the fuel line… or get into the vehicle and remove the fuel pump (with screwdriver) and then have access to fuel line.

======================
As an FYI, when jumpstarting a car.
1) Connect a positive/red cable clamp to the positive/red (+) terminal of the dead/bad battery.
2) Connect the other positive/red cable clamp to the positive/red (+) terminal of the charged/good battery.
3) Connect a negative/black cable clamp to the negative/black (-) terminal of the charged/good battery.
4) Connect the other negative/black clamp to the metal ground of the vehicle with the dead battery. You can use the engine block or another metal surface of the vehicle away from the battery.
5) Start the car with the charged battery. Wait one or two minutes and try to start the car with the dead battery.
Assuming the car starts – simply reverse the entire order:
Remove the black negative clamp from the ground of the vehicle needing the jump.
Remove the black negative clamp from the battery of the assisting vehicle.
Remove the red positive clamp from the battery of the assisting car.
Remove the red positive clamp from the formerly stalled vehicle.
How to Jump Start a Car Without Cables
If you have a standard transmission car, you can jump start that bad boy without using cables. Here’s how you do it:
1. Find a stretch of clear downhill road.
2. Fully depress the clutch and put the car in first gear.
3. Turn the ignition to on.
4. Take your foot off the brake and start rolling down the hill, leaving the clutch fully depressed.
5. Coast down the hill until you reach 5-7 miles per hour.
6. Release the clutch quickly. You should feel the engine turn and start. If it doesn’t start the first time, depress the clutch and release it again.
7. If you don’t have a hill, get some of your buddies to give you a push and follow the steps above.
