I have a 2010 Yukon and about a year ago a gas attendant overfilled it with a little over a gallon after it was already full since then it clicks off every couple cents I have replaced the purge valve,charcoal canister,vent valve, filler neck and had a mechanic swap all the hoses, gas tank and other solenoids from a Yukon he has and nothing has worked does anyone have any ideas?

If the charcoal canister puked all it guts in the tank you’ll have to lower the tank, pull the pump, blow out the lines and swab the tank.

It’s also a good time for a GM OEM pump and sender that has a lifetime guarantee. About $200 on rock auto or parts geek.

It’s a job you only want to do once. I did mine about three years ago and haven’t looked back.
