Got fuel pump

[Gt mam]

Does anyone out there how to replace the fuel pump on my 1989 Celica 2000gti st162 it’s not under back seat only the sender is in cut out above tank . I thick it is further back but how do you replace it or even check it.

Is the fuel pump bad ? Any fuel to the rail ? Any fuel to the filter in the engine bay ? Power to the pump ? Power to the fuel relay ?

Do you have any pictures ?

Edit. It looks like you have to drop the tank

No fuel reaching filter in bay  seem to have power to what I think is pump feed under seat next to sender unit I assume tank is behind that
