So I replaced the fuel sending unit this weekend. It was sort of a process and I definitely had some issues like usual. But I did replace the screws that come with the unit with new #10-32 1/2" screws from Home Depot. I also bought new brass washers. After I installed the unit with these news screws it started to leak from each screw. So I put some thread tape on the screws and now the leaks are gone. Just an FYI for someone putting new screws in when replacing the sending unit. The new screws did appear to tighten better. So overall a good choice. Another item done on the list.
