Based on some feedback I've received, today's fuel tank sending units are not reliable/as good as originals. Here are a couple of pics of my original sending units. The copper point/tip has worn over the years and now is impacting the ohm resistance. Anyone repair originals or know if there are rebuild kits available?

If I need to replace with a new one... any recommendations on brand?
