Can't find replacement o-ring for 1989 f-150 5.0 psps
What would be an acceptable replacement o-ring for the power steering pressure switch on a 1989 ford f-150 xlt lariat 4x4 5.0 automatic? All the auto parts stores and dealerships i've checked with sell the complete switch, but not just the o-ring by itself.

IF NEW PRESSURE LINE DONT HAVE NEW O- RING THE DEALERSHIP WILL HAVE IT.
I have no experience doing this conversion myself but that code should have nothing to do with the engine itself. The code indicates that you're having a problem with the power steering pressure switch (psps). I suspect that the connector to it got left of or damaged during the engine swap. The psps senses when the steering system is loaded, such as tight parking turns and then tells the computer to increase idle speed so that the engine does not stall. If the wire to the switch is left off or damaged, the code will set. You'll need to inspect the high pressure line coming from the power steering pump. Somewhere between the pump and the steering rack you will see a small oil pressure switch with a couple of wires going to it...or at least it should, the connector might be hanging somewhere near it.
SOUND LIKE POWER STEERING PRESSURE HOSE LEAKING.COPPER TUBING IS TOO SOFT METAL FOR POWER STEERING AND BRAKES SYSTEM.BUY A PRESSURE HOSE AT ANY AUTO PARTS PLACES LIKE AUTO ZONE OR ADVANCE AUTO PARTS. PRESSURE HOSE SHOULD HAVE O-RING COME WITH IT.

Place the power steering pump pulley on the power steering pump shaft and install Power Steering Pump Pulley Replacer T91P-3A733-A. The small diameter threads on the tool should be engaged in the power steering pump shaft. CAUTION: Do not apply in and out pressure on the shaft. Pressure will damage the internal rotating group.

What are we talking about? Preasure side of AC compressor pump?
Power steering pump?
If AC, then possibly from a leaking AC-high preasure switch on the back of the compressor. The leak could be simply the O-ring. You simply unscrew it and install the replacement making sure the O-ring is good and in place. The switch can leak also. This part is hard to find accept at the dealer. It has a 4-wire connector on it.
I had the same problem. You can not replace that o ring. You have to replace the complete hose ***. They redesigned the hose to fix that common problem. To bad the customer has to pay to replace a poorly designed part.
