I have a 2004 sentra 1.8.
The past 2 times I have tried to pump gas into my car.. The gas spits back
up and pours right out of the hole while I am pumping gas. The tank is only
a quarter full. Does anyone know why?

It may just be the gasoline 'foaming' too much as you pump it. I admit I'm
not too sure about this phenomenon, but it happens to me sometimes - the
auto shut-off clicks off when I first start filling the tank. (Maybe the
warm temperatures have something to do with it.) Try filling the tank more
slowly and see if that helps.

Could it be that the tank vent hose (pipe) is somehow kinked? This hose
goes from the tank to the filler neck and allows the air from the tank
to be taken to the filler neck precisely to prevent your problem from
happening.

If i am not mistaken, there is also a fuel check valve that goes from
the tank to the carbon canister. If the check valve is not working you
could also experience the same problem.

Good luck!

that they're metal.


unlikely. What is suspect is that a lot of fuel pumps are more
sensitive to back pressure. And many cars have a very sharp angle
from the filler neck into the tank. If you don't fully insert the
pump nozzle into the filler neck, it'll backsplash and cause the pump
to shut off.

Precisely that is why I said hose (pipe)

I would expect the guy to know how to put fuel in his car.

Try pulling the gas nozzle out about an inch. It might be too far down the
tank and close to a bend causing restriction of flow and the nozzle sensor
trips thinking it is full

Why on Earth would someone write to a FORUM with a problem like this?
Call a DEALER and talk to the service dept. THEY should know and
won't charge you to tell you what causes the problem!
