Okay took my own advice and checked the repair manual 180 is correct there are in fact two mechanical check valves in the filler neck one is Midway of the filler neck and is called fuel filler tube check valve and the other is at the bottom of the filler neck tube and is called fuel tank overfill check valve and in conjunction with those valves there are two other mechanical valves that work in conjunction with the EVAP system and they are called fuel tank vent / rollover valves, also as part of the EVAP system there is a fuel vapor pressure relief valve that is electronically controlled I seriously doubt it is the problem, for me I think it is either one of two problems either the fuel gauge is wrong and malfunctioning or the overfill check valve is stuck closed. I believe it's the overfill check valve. 🤔 Still thought the match ideal was funny 😂 but I guess I shouldn't say those things some people may take me serious.
