i just did a sending unit today with crap results. but what i found was some gas in the float that held it down. check yours. also check the grond and the sending unit wire for good connections. other than that i dont know. i curse the replacment s/u's so try to avoid them.

You may have a bad connection at the firewall bulkhead connector. I'm not sure how the Dart is setup but the power to the fuel sender should come through the connector on the firewall. Pull the connectors apart and check for corrosion or melted terminals. Might also spray them down with WD-40.
