84 deville fuel filter

Anyone with knowledge of where the location could be? There was a new fuel filter located in the trunk which I cross referenced and it is the correct one. It is an inline filter, but I have not been able to locate the old one. I am aware it could have been rerouted to either on the passenger side near the a arm or a screen from the throttle body. Or perhaps inside the fuel pump. I have found a filter that is routed to the exhaust before the catalytic converter but Im not sure this is the correct one due to its outbound location.

thanks in advance
