The sump on mine has two outlets, one which is plugged. I just take the plug out and drain it into a oil drain pan.
I would guess that yours only has a single outlet? take the line off, fill a drain pan, put a plug in it til you dump the drain pan, remove plug, fill drain pan, replace plug, repeat til empty.
Or maybe make a drain line with a barbed fitting, fuel line, and a 1/4 turn ball valve on the other end. You wouldn't have to keep crawling under the car.
Or take the fuel line off at the front of the car and use the fuel pump to pump it out. You'd have to make a small hose up again to get it out of the engine comp. When the pump cavitates, shut it off and remove the fuel line from the front and finish draining the tank.
TOO MUCH IS...JUST ENOUGH
fine. I'm out. I don't need this place.
