91 5.0 Power Steering Pump Leak

I'm 99% sure if you pull the fitting back, there is a rubber O-ring in the fittings also. This is probably the source of your leak/drip. Where did you find your Teflon seals? I found mine at Napa but no one else had or carried them ... they just looked at me strangely. Ending up buying some extras at the time since I was not sure if I would find them in the future. Check for that O-ring under the fitting and replace it .....

Each hose uses an O ring on each end to seal them. The hoses will swivel when they are installed and tightened into place. That is why there are O rings on the fittings. The O ring is the part that actually makes the pressure seal. If you slide the nut all the way back as far as it will go, you will see the O ring and the groove cut into the center section of the fitting.


Sometimes you will get some white Teflon rings with the pump or rack. The rings go on the threaded part of the fitting to reduce or prevent small leaks. They are not meant to seal the pressure part of the line or substitute for the rubber O ring. Heat the white Teflon seals in hot water and they will be easier to install. You can install the fittings without them and not have any leaks if the O rings seal good.
