I have a 1/3 of a tank of old gas and I want it gone. Driving the car until it is empty is not an option ... it's currently up on jackstands. I don't want to idle/rev it for 40 hours! I installed a new gas tank last November. This gas tank must have some kind of baffle/screen or something about a foot & a half down the filler tube. I tried putting a 1/2" hose connected to a vacuum pump down the tube about 20 times today and it hits a "wall", therefore I can't siphon it. When I pull the hose out, its not even wet. There is no drain****. I don't want to drop the tank, unless I have to. Does anyone have any suggestions on how to drain it?
Thanks, Darryl.

When I was a teen and needed gas for my mini bike, I would remover the fuel line from the carb on Moms car, stick it into a javex bottle and the start the car and let it run filling up my little bottle. Usually got a gallon before the carb ran out of fuel!!!
You can try the siphon trick as well on the fuel line but am not sure how it would work. Other than than, an electric fuel pump before her own fuel pump and let her go!!!

Do you have a way to put a couple of pounds of air pressure in the tank? If so, do that and catch it at the hose that is on the fuel pump inlet. That is how we used to do it in the shop,

(lol) Mom and Dad knew what I did.... They weren't always happy when I took it to the extreme though!!! But with todays cars with EFI, unless you have a fuel pressure gauge or the talent to disconnect the fuel lines and then power up the fuel pump, it will be a lot tougher unless, you still have a car with a carb!!!
I do like the above ( Vincent ) , except I have a 1 litre bottle with a hose and fuel hard line attached to it. I fill the bottle and hang it from the hood attached to the carb , this gravity bottle feeds the carb. I run the unhooked pressure side of the fuel pump into a jerry can to catch the rotten fuel.
Nice thing with this is, I add fresh fuel to the tank once it's pumped down, slosh it around a bunch and repeat pumping till empty again. gets the tank pretty clean if they aren't too bad.
this beats changing fuel filters and emptying the float bowl....

Is the car entirely up on jack stands? If so, I have a suggestion that worked for me:
Remove the gas line at fuel pump.
Put the fuel line into (or over) a shallow container. I used an oil catch pan.
Take out the jack stands holding up the front of the car (so the nose is down).
Remove the gas cap on the tank.
I didn't even need to suck on the hose to get it flowing. Gravity eventually did it's job and pushed the gas through the path of least resistance. You may not have to remove the cap if your tank is new and your vents are good, but it helps with the flow.
I'd have another catch pan handy to swap out if the other fills up, as well as something to stop the flow of fuel. My fuel line was rubber, so I found a bolt big enough to plug it.
However you go about it, good luck. Just don't be smoking while you do it, or dump the gas down the sewer (if you're in the city).
It should empty the tank. I'll connect it to the tank sending unit. Hotrod Auto Supply located in good old Sask.

When I emptied my tank, I took the hose going to the carb off, and used a jerry can and turned the car over til no more gas came out. Also done it using compressed air into the filler, with rags stuffed around to seal, and unhooked the hose before the fuel pump, it forces the gas thru the lines and out the hose.
