Default Sending unit wiring harness

I am replacing everything around the fuel tank in my 74. As I was putting it back together I realized the metal end on my old sending unit was rusted inside of it and can’t get it out. Anyone know why type of connector this is called? I prefer to get a pigtail and splice it in versus buying the whole harness.

Pretty much impossible to find in any stores, but available online from a number of places.

Unlikely you find a length of Black 16-14 gauge wire and that Delphi single connector housing already crimped ...
Now, if you don't care if the wire is white and the single wire connector housing is white Pico #5665PT...Amazon about $10.00
The white connector has the slot that you original doesn't, but it is a standard series 56 connector housing for a F/M terminal...
If you want the correct connector housing & terminal here is a ebay link:

You will need to crip the new terminal to your harness...

The above picture wasn’t exactly what I needed, but it pointed me in the right direction. I learned something today!

I got a crimping tool too.
