Hello, I have a 2007 hummer h3 luxury package around 56000 miles on it. the problem Is when I fill gas and its full and the pump shut off automatically. it spells gas from where the bump id plugged. I checked the vent hose and its not clogged I took it off and did compress air in it and it was fine.. what the problem might be? please I need help I don't know what else to look at to fix this issue.

thank you

WHAT??!!

 

 

You need to explain your problem in more detail

 

dont top the tank off. mine does the same. once its full stop. dont top off. there is a overfill slot that fuel will leak from.

 

Not sure what you are writing? If you are having a problem fueling, you need to replace the vent valve.

 

I replaced the vent solenoid and it still does it.

I don't top it off, I just put the pump and pump the gas and when the pump shut off. it spits a good amount of fuel out....

this video show how mine does its the same



I ran out of ideas what else could be the problem, I checked the tube that attached to the filler neck, and its clear, I replaced the vent solenoid with brand new one with its hose and still does it ... please help

 

Try a different gas station?

 

 

Have you tried what the HumbleMechanic suggested ?
Try filling with the gas nozzle at a lower fill speed and stop when near full
