power steering hose leak

[cigar-]

I have a 1971 C-10 truck with a 350 CI motor. When I put the new motor in I bought a new pressure side power steering pump hose. Yes, I made sure I bought a good one. It is made by gates and hopefully not some Chinese made piece of garbage.

From day one I've had a leak on the high side, no matter how tight I wrench the nut on the fitting. I've had the hose out/off and looked at this at least a half dozen times. It's difficult to see if the flare on the hose end matches the seat in the steering box. All I can hope for is that gates knows what they're doing. Maybe not.

The steering box on the truck looks as though it's the original. There's no way that I know of to tell if it's been replaced. My eyes go by the oil and grease that are caked up on everything else on a 43 year old truck!!

Is there supposed to be a small o-ring that sits down inside to help seat the fitting? Am I missing something? Heck....go ahead....call me stupid if you have to. I just want to get my truck back on the road without leaking power steering fluid everywhere.

Thank you in advance.....
