Leaking power steering hose. How to seal?

[Dr Red]

Does this power steering hose bolt seal with a gasket or crush washer? This is a leaking bolt on my ‘93 FZJ-80’s power steering pump. There is dye in it, illuminated with a UV flashlight.

There is a O-ring on that suction tube.

Thanks for the tip.

Checking various o-ring kits, there are rubber, and fluoroelastomer at my local parts store. Which material is preferred for this application? I’m intending to replace the power steering fluid with ATF.

Viton or EPDM is what most auto stores will have which is acceptable.

The correct O-ring can be purchased from Toyota.

Went with what O’Riley’s had on the shelf.
Rubber is good to 240 degrees so we’ll see if it lasts. The closest size was 10mm ID x 14mm OD x 2mm W

New vs. old

Cleaned it up and replaced the hose too as it was as stiff as cedar kindling.

Topped it off with ATF, and am currently test driving. Seems good so far. Not dripping yet.
