Engine flooded-empty tank to full tank?

BuckeyeZ · 05-17-2016, 12:10 PM

Just a question: Why fill it so full that you can see the gas in the neck? That is way too full on any modern car. My guess would be that you overfilled the tank and that will mess with the vapor recovery system that is a part of modern emissions. This probably flooded the on-board vapor recovery system and dumped raw gas back into the canisters instead of vapor.

My suggestion is that you don't overfill your tank and see if it happens again.

Stop when the pumps shut off.

^ this. I have seen it multiple times on different cars. If you've saturated the charcoal canister then you have screwed yourself and will have to replace it. Very expensive when people do it to the ML Mercedes where it is integrated on top the fuel tank. Hopefully the z's isn't.
