Power steering pressure switch

[Rwainscott]

Hello all, i have a 07 4.0. I've been seeing a leak underneath the car of power steering fluid, that is coming from the sensor, every place I look at for this sensor doesn't have an oring, does the switch require one, or is it a flared connection, everywhere i look im getting mixed reviews on what it would be, I would appreciate any help

You can probably pick up an o-ring that would work from Harbor Freight or a hardware store for a few bucks. If a dealer sells it separately then likely $15 - 20.

I just verified with parts. The FORD switch does NOT require an o-ring.
