I have never tried to siphon fuel out of my 126 but if you need to get the gas out of the tank, go under the car and in the fuel pump area, trace the hose that goes from the tank to one of the fuel pumps. remove that line and you will have gas gushing out. Make sure to have a large pan or two on hand.
