I have a 6 speed Enthusiest with 1400 miles now.
3 times now the car wouldnt hold more than a little under half a tank of gas (acts like a full tank at the pump).I can then drive a mile or two and come back to the gas station and it fills up just fine!
Is there a vent problem with these? No check engine light on or any drivabilty problems.

 

yup i had those problems a couple times. ONly filled up 3/4's of the way. only happened 2-3 times so far. got 3000+ miles

 

I've filled up 4 times now and haven't had a problem yet. Not sure if this makes a difference or not, but my dealer told me to completely remove the keys from the ignition before fueling.

 

The keys???????????


I have had the car 6 months and have experienced this a great many times. I spoke with people who have the 300ZX, and they have had the same problem. You have to pull the nozzle out part way. The bend in the tube hits the gas nozzle and makes it act as if it is full. I have done this and have had the problem only once since then. You may have to slow the gas flow too.
