Where is the flap in the fuel filler hose?
It runs from the nozzle inlet over the frame rail and to the inlet pipe on the tank. The flap was not in the filler hose. Nor could I feel it as far as my finger could reach into the tank pipe. If the flap is in the truck, it is in the tank.
What is the flap on the fuel pump called?
The flap is called a “rollover valve”. It supposedly keeps gas from flowing out during a rollover. I don’t think it can do any harm because the fuel pump inlet is protected by a “sock” that acts as a filter of sorts. That valve is missing in a lot of vehicles so…join the club. Thanks for that.
Where is the check valve on a fuel filler?
THAT valve is at the base of the filler tube. The flapper, at the top of the filler tube could fall and jam the check valve. If this happened, it could cause an EVAP DTC code to set and the check engine light to come on.
Why is the fuel fill control valve stuck?
The fuel fill control valve may be stuck. The fault that you have may be due to a vapor leak in the fuel system. First inspect the vapor lines from the tank to the vapor canister and to the engine for split hoses at the ends. Thank you for the advice! I don’t know how to work on cars, so I’ll have to bring it to a mechanic.
Where is the flap in the fuel filler tube?
The flap, at the TOP of the fuel filler tube, is NOT the roll-over (or, check) valve. THAT valve is at the base of the filler tube. The flapper, at the top of the filler tube could fall and jam the check valve. If this happened, it could cause an EVAP DTC code to set and the check engine light to come on. Have light?

Where is the fuel filler flap on my 2003 Tundra?
The spring loaded flap in the fuel filler neck of my 2003 Tundra has gone missing. I’m almost certain there was a flap there, but now it is gone. Is it possible for it fall into the tank?
