Hello and Welcome to Justanswer,

My name is XXXXX XXXXX I am here to try and assist your with your question.

The best way to check the sending unit is to unplug it from the the sender and ground the wire with the ignition key in the on position. The gauge should peg to full if it does, the sender is bad.,

Is there any way to get to the sending unit without dropping the tank? Is there an access door in the trunk?
Unfortunately no there is no way to get to the connector with out dropping the tank.
