Power Steering
Have blown power steering hose off at the pump three times now. 2001 F350 4x4 diesel. Truck now at Ford in Puerto Vallarta waiting for them to look at it manana! Hose blew fitting at pump repaired and drove 30 km no problem. Parked for 2 days drove one block and blew again, went to ford got new fitting replaced and refilled and blew again, when engine was revved and wheel cranked. Oil was very foamy at that point. Towed to ford and here we sit sunny and 80 degrees. Sounds great but not much faith in ford. Interested in any comments.

O-ring, like the white plastic ring on a threaded fitting, or a quick-connect fitting with a black rubber sealing o-ring? And yes, you should bleed the system. Easiest way for me is to disable the motor so it won't start and just crank it in short intervals, like a second or two, and just keep adding fluid between cranks until it doesn't drop anymore. Not exactly a scientific way of doing it, but I've never had a noisy pump (that wasn't noisy before I started) or any other problems when I was done. But you can always find the vacuum bleed adaptor that goes in place of the cap and do it that way.

Mityvac sells a Ford power steering adapter that allows a handheld vacuum pump to be used to extract air from the system. I highly recommend it. Driving to remove the air can make the steering VERY hard and may take a few hours of driving to purge all of the air.

What do you mean by hose blew at the fitting?
Did the rubber of the hose tear open?
There is only one fitting that threads into the pump. If the full threaded fitting came out of the pump, then you had a bad hose (unlikely to happen 3x) or there is something wrong with the female threads of the pump.
