The pump seems to think my tank is full b/c it keeps shutting off after a few seconds. I have to pull the nozzle almost all the way out and then drizzle the gas in. I put in 15 gallons like that before it started to overflow. I bet there is some thread on this but a quick search found nothing. Any suggestions?

Damn, this is actually a problem with the gas tank and stuff? I always thought it was either the pump itself or gas, not the car.... I never had this problem yet with the Lex. I have had it on other cars. Slowly ease it to full output on the pump and it stay at full output until it fills up....

if you over fill it once and I really mean just once like you described where the gas comes out, the charcoal canister gets filled with gas from the vent line and you will have all sorts of issues like that for a long time, and that gas also get sucked into the intake and can cause rough running. you may need another canister if thats what happened.

the fuel should never be filled to a level above the vent line hole which is towards the top of the filler neck. If you had fuel coming out your filler neck, chances are a good amount of it is in your canister now. if you experience rough idle or stalling thats what you will need to check. if not then you may be lucky just fill it to no more than 1/2 to 3/4 tank for the next couple of fills and see if it can work out. do not top off on cars that have charcoal canisters, it will just cost you more money in the end.
