There are 2 basic fitting styles on pa pumps/hoses/boxes:
Inverted flare
O-ring
The Toyota boxes and pumps were used to use inverted flare fittings. Most of the domestics used to as well but a lot of them switched to the o-ring fittings many years ago.
We haven't had issues with pump or hose leakage.
If your pump is leaking between the HP
fitting and can, then I would suspect a cut or damaged o-ring. The fitting should have been installed already when you received the pump. There's really no need to remove it. But if it's leaking, then take it out and check the o-ring. I would not use any sealer but a light coating of ATF or PS fluid to help the o-ring slip in place.
If your leak is between the HP fitting and the HP hose, then the flare isn't seated properly. I'd remove the hose and inspect the flare for any imperfections. Make sure to use a flare wrench to tighten the hose fitting properly.
