My 2000 LeSabre has begun puking gas at fill up. I have the gas gauge
sending unit problem and using my trip meter as a guide, all has been fine
up to this point. At my re-fill mileage, I figure I've got about 3 or 4
gallons left in the tank so it's not empty. Fuel has to be put in SLOW up to
the 5 or 6 additional gallons point. After that I can set the fuel auto stop
tab and all is fine. Is this a venting problem? Why does it stop? What's the
fix? Thanks.

This problem can be caused by "topping off" the tank too much. Gasoline gets
into the vent system and carbon canister. This restricts the flow of air for
venting.

So check your evaporative emissions venting system (also could be a problem
with a bad valve), and don't top off the tank.

Not just GM either.

It is happening at the start of the re-fuel, not the end.
