How to syphon gas from a 240 Volvo wagon?

I filled up my Volvo just before it took a dump. I bought a syphon and it won't go in all the way. Can someone tell me how to retrieve the gas? I put in $48 dollars worth and don't want it to go to waste.|||if you can get it on jackstands there is a screw on the bottom of the tank that you can undo.It is a drain.Or open the access hatch through the trunk remove the sender unit and put your syphon in there or buy a longer syphon.|||240's don't die !!!!
