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.

Difficult to fill fuel tank. Fuel pump shuts off constantly as if the tank is full. Fuel tank is nearly empty. Believe problem in vapor canister system.


This is a common problem when filling up especially with the smaller nozzles on modern pumps. You could try pulling the pump out slightly say a third as this often works, also tipping the nozzle can help. The system will stop pumping if it senses back pressure through overfill. I hope this will help you to solve the problem.

PO441 code comes on- Evap purge control valve. also, when filling the gas tank, the nozzle on the gas pump keeps shutting off before tank is full.


Try not putting fuel nozzle in so far. Fuel flow cuts off on back pressure of the air being displaced by the fuel when filling. Can be a problem with narrow neck tanks and some fuel fillers are more sensitive than others.

Gas tank will not fill up on 2001 ford expedition


Gas as in gasoline or gas as in LPG gas? If its petrol, the fuel sender may be out of adjustment. (Usually means a new sender) If its LPG, the fuel stations are set to automatically shut off at 80% full. The gas tank will never actually be full to the brim but the gauge should be showing full if the gas nozzle keeps shutting off. Have a look on the LPG tank itself, they have a little gauge on them which shows how full it is. I have 2 tanks on my car , when "full" or when the pump shuts down, the tank gauges show just under full but the gauge on the cars dash shows full (2005 BA Ford)

When pumping fuel nozzle continuously shuts off on my 2004 toyota celica


sometimes the sensor in the gas pump can be tripped if the nozzle is put too far into the tank, try holding it out a bit farther so the end of the nozzle is just into the tank's opening

When putting gas in my 2004 Kia amanit the fuel nozzle kicks off. How do I locate and fix the problem


HI Bridgette,

Due to the different shapes of fuel tank filler necks in cars & trucks, it may be necessary to vary one or more things to allow fuel to flow uninterrupted until the tank is really full.

The main problem can come from the new "vapor recovery" gasoline pumps. These pumps and hoses actually recover gasoline fumes from your tank as the liquid gasoline displaces the air / fumes in the tank is it is being filled. If gasoline flow is started at full blast, it can splash back slightly, causing liquid to be pulled back by the pump - so it shuts off. So, start with a slow rate of filling and gradually increase flow rate to maximum over 5 to 10 seconds. If it still shuts off, try some of the suggestions below.

First, don't fill at maximum flow rate from the pump - that is, don't set the nozzle for wide open. Select one of the other "latches" on the handle instead of the fastest flow and let the tank fill entirely at this rate.

Second, you should experiment a bit with the length of nozzle that you push into the tank's filler neck. If you push it in too far or too little, the pump nozzle can do what you're describing.

Third, try twisting the nozzle slightly so that it doesn't hang straight downward - a little to the left or right may provide a solution.

Lastly, try a different gas station. Their pumps may not be so picky with your tank's filler neck.

Good luck!

I can no longer pump gas into tank continuously. The filler backs up and shuts off fuel even when using gas pump manually.


You may have a problem with the fuel tank vent valve. This lets air into the tank as you use fuel and allows air out of the tank as you refill with fuel. If the valve is plugged or stuck shut the fuel nozzle will kick off as you try to refill the tank because the fuel can't get through the fill neck and into the tank as fast as it's being pumped in and will back up high enough to kick the nozzle off. Hope this helps and good luck!

When fueling car fuel nozzle cuts off only allowing a couple of cents to go onto tank at a time any help with this problem


The fuel nozzle on the pump is designed to shut off automatically when your tank is full. What is probably happening, is the fuel is backing up in the filler pipe because of the bend in it.
Try repositioning the fuel nozzle when you fill it. Usually everyone pushes it all the way in. Try pulling it back an inch or two.

1995 Saab 900 Won't Take A Fill Up


Sorry if this gets posted twice. I have a 95 Saab 900, which I just acquired. I can get only about 4 or 5 gallons in at a time. The best analysis I found was this one where the man pinpoints a stuck valve in the gas tank, and tells of what he did to address it.: http://www.quasimotors.com/9_5_gas_fill_prob.htm

99 mercury tracer won't let gas into tank from station nozzels.


Modern gas pumps have a sensor that shuts off the flow of fuel when the tank is full or it senses near the nossle tip. They also have a back splash guard that keeps fuel from splashing back on the handle. If you have some sort of flap inside your fuel tank mouth the pump may sense that the tank is already full or the back splash guard may be keeping the nozzle from fully inserting into the tank causing the same out come. I have a 1977 Triumph Spitfire that requires me to hold the fuel pump in place or the fuel won't pump. Try holding the fuel nozzle in place and see if that makes any difference.
