The fuel keeps coming back up? Are you drinking it?

What does that mean?

Maybe you would take the time to type out a question with enough information for someone to understand. What you are talking about.

That means either there is an obstruction in the filler or the vent system is restricted and nYou may have to remove the fuel tank to find out.

What do you mean by the obstruction in the filler? Is it that there is something stuck in the fuel line?

The fuel tank might not be "breathing" correctly. If pressure builds up in the fuel tank, fuel can get pushed up the filler neck.

If you can not fill the tank because the fuel keeps pushing back, then the breather hose might be restricted.

I attached an image of the fuel tank / system.

#3 is the filler neck
#7 is the breather hose
#24 is the rollover valve for the EVAP system

A problem with #24 (or the hoses) can cause pressure to build (incorrect venting of the tank).

A problem with #7 will cause filling problems when adding fuel to the tank.
