oil pressure sending unit
I called Ford on this subject because I was going to buy a car in AZ and the seller told me that it needed a new sending unit because the one in it was leaking. Anyway, the Ford tech I talked to said it was on the passenger side of the block and that it was a driveway job, all you need is a jack, a 9/16 or 5/8 open end wrench and thats it. I never ended up actually doing the job cause I didn't buy the car. I bought the part though at NAPA for $11.63. Cheap(finally something). By the way, Ford quoted me $35.00 to do it for me plus the part cost!
