How do you siphon gas from out of 1998 Jeep Grand Cherokee?

Answer 1

You don't. Go buy some gas and quit siphoning gas from your neighbor's Jeep Grand Cherokee. Now, if it's yours, then you have to get by that little door just inside. Therefore, you need a long enough hose for your siphoning gear to get pass the door, but strong enough to hold the door open so it doesn't pinch your hose.

Or you drop your fuel tank and pull it from there. The key to siphoning any fluid is to have a hose with some kind of vacuum to pull the fluid and then a container set low enough so that gravity can do the rest. You can do the old suck it out or just go over to your auto parts store and spend the money on a siphon set up. Far easier and no fluid in your mouth to spit out. And if you spend the money, then you may have an easier time of it and be able to reuse when you need to siphon another fluid like coolant.
