In my stock 52 8RT/8AB I need to replace the oil pressure switch and this is the only one I'm finding,and it does not say what pressure it's for 80 or 50 psi. OIL PRESSURE SWITCH - SKU#:Motorcraft SW-1547B
Does anyone has a part number for the 80 psi one,or are they one in the same for motor?

What engine do you have? I don't think that is the correct unit, that is for a later model vehicle.

From VanPelt site: Sender Units - Oil Pressure 41A-9278 is 80psi

The motor is the original Ford, 8AB/8RT Flathead 239 cubic inch.
It looks to me that the 41A-9278 is what I am looking for.
Thanks for the help

80# is correct, but I have always been baffled by the gauge reading 0 30 80?
I say it should be 0 40 80. I been through a dozen senders and none match
my mechanical gauge Ex.- my mechanical gauge reads 45# hot and dash units reads
below 30#. So back to the cabinet. I try a sender that I know was from a 1970s
Dodge 318 / 360. Perfect: now the dash gauge reads between 30 & 80 ( 0 30 * 80)
I have no part no. or the box for this sender but its not like the Ford or hat, its
almost 3 inches tall same tread but nut instead of screw for the wire. sam
