Just to be clear, by assembly you mean you installed the whole shebang, pump, sending unit and strainer?

If so, there’s the possibility that the connection is bad, the arm could have been bent when inserting in to the tank, causing a loss of connection.

Harness/plug could be corroded or damaged.

Look at the gauge as a last item. Unless, there is a salvage yard close to you, grab a new (used) cluster and swap it in. But, to just diagnose an issue that could end up rather expensive.

There is always the possibility that there is a bad solder joint, or wire in the cluster.

My point is, it could be any number of things, just offering you some ideas and starting points.
