Fuel fitting threads
Depends on what the pump "is." Can you post a good clear photo? Some of the Carter aftermarket hi perf. pumps are pipe thread. There is no seat at the bottom, the hole goes clear through. You want sealer, and be careful tightening too tight, as pipe thread is tapered, and can spread and crack a casting
Most OEM pumps are inverted flare. They have a seat at the bottom and SHOULD NOT USE sealer, as the tube seals on the flare
Inverted flare
This adapter is inverted flare on the near end (mates with tube above) and pipe thread on the other
You should not need nor should you use sealer on inverted flare
