S14 Fuel Pump Assembly

[KA-T...MAO?]

I know this question probably gets asked a lot. Has anyone purchased an aftermarket fuel pump assembly? If so what kind and from where did you order it?
Currently having gas gauge issues. I’ve read about the fuel sender unit falling off into the tank. Was wondering if there another route to go. Thanks

Have you pulled it out and looked at it?
I was having issues and pulled mine out and the solder had broke off the black resistor thing
