Can't fill the tank without nozzle clicling off repeatedly.
The fuel spills over and the automatic shut-off doesn't work at many gas stations, so I have to watch the gallons registered at the pump and shut off the pump before gas spews out to the ground. It is also difficult to get gas into the car and I have to set the pump latch to a notch lower than the one that pumps the gas the fastest.
Gas nozzle keeps switching off when filling tank.
My problem is the same. I have to angle the fuel nozzle a certain way for it to fill. Then I have to be careful not to over fill or it will spit out allover the place. I was told it is some sort of value in the tank and they would have take out the whole tank and replace it to fix it, so I will live with it.
Fuel tank hard to fill. Acts like tank is full. Can only add 1/4 gallon at a time, then have to wait 10-15 seconds to add a bit more. Requires 20 minutes or more to fill the tank. Visual inspection underneath looks good - no kinks or damage. Removing the fuel filler hose from the tank and looking into both with a mirror look normal.
When fuel nozzle clicks off it burps out gas onto the ground , problem not resolved so I only fill to about 3/4 full !
Fuel Filling is very slow, one pint at a time.

Two hints: 1) If the engine is running, it will fill normally. 2) If I remove the hoses from the EVAP purge valve (near the battery) it will fill normally. Clearly the vapors are not being released correctly from the tank during filling.

A thorough visual and manual inspection of filler, tank and EVAP area is normal. No kinks, dents, twists, crack, leaks, etc..

We have a problem with the gas "overflowing" while filling the tank. We have to pay really close attention to stop it before it's full so it doesn't spill out everywhere. We have around 137,000 miles now but this has been a problem for a very long time.
