fuel tank will not fillup

post #1 of 5
Thread Starter 

I'm looking for a little information so I can talk knowledgably to my local dealer's shop.

I have a 2007 Chrysler Pacific that will not accept gas at anything faster than the slowest notch on the gas pump handle. At 3/4 full it starts to slow more and will not fill past 7/8ths. Another problem is the gas guage works normally until slightly below half a tank and then drops directly to empty. What could happen to a gas tank or gas guage to cause this problem?

I had an issue similar to this in a wrangler. It's probably the float. Instead of fixing it, we went by mileage on the odometer.

There is a breather tube in the fuel fill area of most vehicles.  If it is kinked or blocked filling becomes an issue.  Imagine pouring gas from a can without a breather hole open, very slow; same thing reversed.

google chrysler pacifica forum and you'll find places to ask owners.

Possible two separate problems. Blocked gas filler air vent might be the cause of the fuel up problem.


A malfunctioning float in the gas tank is the likely fuel gauge problem. I had this problem in an older Celica and the Toyota service dept. guy said it would be expensive to repair because it involves quite a bit of labour to remove the gas tank and get at the float.


I passed on the repair and went with watching the odometer as L&AirC suggested.
