These 95s are really common for fuel leaks at the flexible rubber lines coming out of the tank.

When adding gas in the Jimmy gas is pouring out from line.


You best replace the filler neck so it wont leak, and operate properly. I do not think a vacuum, vapor lock has occurred.

GMC Jimmy gas filler neck leak


Replace your filler neck. It's not hard and when you buy the new one, installation should be obvious and rather straight forward.

A fuel leak is not something to take lightly and it will get worse over time.

Most fuel systems are pressurized (that's why you'll sometimes hear a hissing sound when you open your cap) so if your filler neck is leaking it can throw a code.

I have 2005 GMC Envoy. I noticed the gas


The new design filler neck on newer gm vehicles don't have a flap. The flap was just to keep stuff from falling in. I've had problems with the fuel sending unit in the tank on these vehicles.

Can't put gas into the gas tank . I have a 2001 gmc jimmy and have had alot of trouble puting gas into the tank ,I am only able to put about $2.00 in and then the gas pores back out.


I had this same problem....I had it checked out a few times and got many different answers and spent money for fixes that didn't correct the problem. Finally about the 3rd time in the shop they finally found the problem/solution.

There is a pressure purge valve located near the tank that is supposed to release the pressure in the gas tank when you shut off the engine. My valve was bad, it wasn't releasing the pressure when turning off the car. Since the pressure remained in the tank, it forces any new gas trying to down the filler neck into the tank back out. I have heard that this is a common problem with the Jimmy.

I had this part replaced and now I can pump gas as normal.
