Sometimes this forum is like watching a bad episode of Letterkenny....
@Raider L , you can't figure out what's wrong without removing it. Dunno why folks are talking about the crimp to the hose and the hose itself. Maybe lack of reading comprehension since you clearly said in your first post
"my power steering return hose is leaking
where it screws into the top of the sector. ....... And I've already put a wrench on it and it's tight. I don't want to over tighten it so I was going to take it loose
and look at the end that goes into the sector to see what I can see. I can't imagine what would cause the return line
to leak at the sector. ......"
I have no idea what hose clamps and gaiter hose (Gator brand hydraulic hose??) have to do with this.
The fitting on the return line is one of 2 designs and appears the old squares like yours is the no O-ring design.
Also, brand spankin' new return hoses are somewhere between $6.29 and like $15 online. So I wouldn't spend 10 seconds trying to "fix" a $6 40 year old part.
I'd buy a new return hose and a fresh bottle of power steering fluid before even touching it with a wrench again.
Just a suggestion.
