I went to one gas station they had these new kind of nozzles but I was only able to pump about $5 because it kept stopping. Then, I went to another gas station and the same thing happened. Could it be that the fuel tank has dropped? Why does it keep stopping?

Re: Pumping fuel problem
It sounds as though the vent tube is clogged. Check the fuel inlets for collapse. Also change your fuel filter. Since the system is sealed also check the evap system and solenoids for proper function.
Hope this helps;

normally the pump stops the nozzle from pumping gas,your gas tank is full. bypassing this safety feature is not reccomended as the tank will become over pressurized and eventually you will smell gas around your vechicule due to a blown seal between the tank and filler neck.
You might not have to change the pump at all. Get the fuel filter cleaned thoroughly, change it if required(its quite reasonably priced) and since this has MPFI (multi-point fuel injection) engine, either clean it by adding some nozzle clearing fluid or get the nozzles properly cleaned at a authorized service station, where they can connect it to a PC to check the status of the tiny holes of the injector nozzle.............................sodeep
The fuel pump is located on the frame undrneath the passenger side rear door.If you have the throtle body injection used on the 305 engine the electric fuel pump puts out about 8 psi.
Sounds like you have a clogged fuel pump. Not that bad to change if you have the special tool needed to remove the fuel lines to the pump. Ask your local Auto parts store for help.
Fuel Backing up in the fill nozzle is most often caused by a restricted fuel tank vent line. This vent line runs from the tank to a charcole filter that stores the tank vapors while still allowing air to pass. It is typically located in the engine compartment. Look for a pinched hose first in the engine compartment. Typical hose diameter is 10 mm or less. If you have had recent work done on the car in the fuel tank area, this also may have resulted in the line being pinched or rerouted in error.
I have had this problem. For me it's usually when the tank is really empty. I worked at a gas station and at times, I'd have to replace the gas nozzles when they wouldn't kick off correctly.. I suspect the problem is that the gas nozzle is picking up more gasoline fumes that are being displaced in the tank and venting thru the fuel filler opening. The gas nozzle detects enough gasoline vapors with it's sensor to shut-off the nozzle. One can slightly adjust the nozzle in the fuel filler opening (or wait a few additional seconds giving time for the fuel vapors to exit the fuel tank)) and it works great.. I do not believe it is a problem with the Blazer. It's a combination of the gas nozzle and the amount of vapor escaping the filler opening with the displacement of vapor in the gas tank. I've had this happen in my Ford Contour.
I hope this helps others.
Not sure if it's a vacuum issue.... I will just push back the rubber seal and input the nozzle....Then it will dispense the gas....Not sure why..... It only happens at certain gas stations.. Good Luck!
