Car is LS400, 2000 model, 200K miles.

Am having a problem where fuels come out on every overfilling of tank with fuel.

Any one has this problem with his LS? How to solve this?

I had googled for this, I think maybe i have to change the
Fuel tank over fill check valve which maybe cracked or damaged.

But i cant see this part in my repair manual!
I had attached page of fuel tank.

Please help!

Maybe you can make a hole in the tank so extra gas can come out....haha. Just kidding.

I think the overfill sensing mechanism is in the pump nozzle, not the car.
Maybe just don't overfill? Its bad for your carbon canister.

Evaporative Emission Control System Vent Control ?

Where do you expect the gas to go ?
If you need to max out km then get a secondary gas tank added or keep a spare can in the trunk.
Over filling it will cause the Evap system to fail and the car to run worse .

Get some plastic Gas tanks in the trunk.
