Gas not filling all the way


Recommended Posts

I have a 2002 Carrera 4S Coupe that never seems to fill up completely at the gas station. FWIW, I usually fill up at Chevrons.

The pump will go until it's about 7/8 full, then stop. Basically, the pump stops automatically before it's completely full. Sometimes, if I can guess how many more gallons I need, I'll top it off, but I don't like doing that for fear of spilling gasoline everywhere.

I had the same problem on my 2003 Boxster S that the dealer could not fix.

Does anyone else have this problem or know what the reason/fix is?

I've searched this forum, but couldn't find anything.

TIA

I have the same car, and mine has the same issue, although not at every fillup. I've tested different pumps and there's no pattern I can discover, e.g., the same pump will fill sometimes and not other times. Strange, but given the sorts of problems we could be having, not much of an issue (at least for me).

I have the same problem with my 2002 911tt. It’s not a major issue, but is annoying.

On some fill ups, after the first automatic stop, if I try to top off, I immediately spill fuel all over the place. On others, I can top off the tank successfully with no problems.

I’ve tried to find some sort of pattern with the fuel pumps, different stations, etc. but have not, which leads me to believe that it has something to do with the car.

Or what I've been doing ever since driving 911's or boxsters.. just turn the gas handle 180 degrees.. Yep that's right, put it in like you were standing on the other side of the hood.. works like a charm and people stare @you like you're from another planet.. haha

Good luck!
