A repro sender seems to work somewhat for some folks and not well at all for others. It is a different technology, so you are kinda mixing apples and oranges. Believe the biggest issue is you are going to get different curves with the different types of senders. You can work with them and get it acceptable at empty which is what most of us are interested in.

Not to much you can do inside other than clean the points. Use a file, not sandpaper! The old ignition files are what you need. The point get material built up on them over time. The other thing to check is the ground at the sender. It originally grounded through the tank itself, but the addition of a ground wire directly from the sender to a good grounding surface can help. You might also want the to check to be sure the sender is the issue and not the gauge itself. You can check the gauge with a battery, at 1.5v or 3.0v and see what gauge readings you get.
