sorry but it looks like you will be in that tank again. pull the pump out and plug it into the car wiring outside the tank and move the float up and wait 60 seconds. if it doesn't move the gauge, replace the sender (with a new one or maybe with the old one, if you still have it) and test it before you install it
it is inside the gas tank, part of the sender unit. you have to take the tank out of the car in order to replace it. while it is out of the car do yourself a favor and replace the fuel pump too so you do not have duplicate labor when the pump goes out next year. before you go nuts, pull the liner or carpeting out of the trunk and make sure your car's trunk does not have a service access to the gas tank. generally gas tanks are mounted under the trunk.
bleed any pressure off at the engine. drain and lower the gas tank, remove the pump install new pump. replace all hoses with new while you are in there and might do the gas gauge sensor too and any external filter nearby. reinstall tank, put in gas, turn on ignition and bleed any air out. go.
Sounds like you have a broken tank or tank connection. The sending unit ( hanger ) has the gas pump and the gauge sender in the one unit htatgoes into the top of thetank. the tank has to be lowered to see. theirs three lines connected with snap on fuel connecters that take a line toolto release them. some methinol fuels will eat the seals out of these and rot the float for the fuel sender. If the tank has been hit hard from the bottom theirs a baffle that can come adrift and run into the hanger breaking the lines as they go though the top of the tank making a leak course you coulda run over something that punctureed and bent the tank.
you'r EVAP system is not purging the system . I suspect it is your charcoal canister located in the left side of the engine compartment located near the master cylinder its a piece of cake to change it just slides up after you diconect the lines .
