Dropping the radiator takes like a minute. You leave all of the hoses connected, remove two bolts and walla. Free space!
Good luck!

OK - you made me look up an old post. The pump body has no check valve but the pump motor assembly does!
From Post # 2 here: http://www.600riders.com/forum/fz6-...uel-pump-battery-charging-brake-bleeding.html
So that explains that. It also implies the OP's **could have** a serious leak where the pump is not seated to the housing correctly or the valve is stuck open OR somehow fuel has a path from the tank to the exit. Like a crack or missing/damaged O-ring.
FWIW: I tend to error on the side of caution and propped the hose up while doing the valve clearance adjustment as it had 5 gallon of fuel which could siphon onto the ground and ruin life as I know it!
