Question Gas Tank Problems??

Recently I have been having difficulty filling my tank, and it has nothing to do with the price per gallon! When starting to pump gas into my 2004 Chevy Blazer, the automatic shut off of the pump activates, like my gas tank was full. But I know it is not, so I try pumping more. This happens over and over, only allowing me to pump about 10 cents of gasoline at a time. At first I thought it was the pump, so I tried another station. New station, same problem. So my thoughts are that something is in my tank or the neck leading into the tank, causing the pumped gas to back up and trigger the shut off on the nozzle.

Has this happened to anyone out there? I would appreciate any thoughts or suggestions. Any information will be helpful when I take this into a mechanic (I am a do-it-yourselfer, but do not want to fool around with the gas tank).

Many thanks in advance,
BGH

I thought so too, but after reading all over Chevy's forums, specifically the TrailBlazer, this issue was very popular. All the threads said to replace the filler neck hoses and problem was solved.

Would it be best to replace filler neck and hose, and also check evap system?
How much time and expense will be involved with this?

Parts will probably run you around $60-100 and less then one hour labor if that.

Replace the filler neck and then see how it fills up before doing anything else.
