What is the difference between the oil pressure sending units of 79-89 5.0 Mustangs and 90-93 5.0's with a pressure gauge?

I found this site which shows different units:

Mine has the old style sender (E4ZZ) in it with the extension tube. Should I replace it with the old style or replace it with the newer one (F3ZZ)?

E4ZZ does not change to the newer part number......so I can only assume that whoever put in that sender put in the wrong one.......

grab a F3ZZ and throw it in.......the other will probably work, but will be "off"......

I had a 1970 temp sender in my 69 and it read on the hot side of normal....put in the correct one and it put the needle in the middle

another note:

per the Ford computer here at work:

"NOTE: On early models the wiring harness from the oil pressure switch included a diode identified as 7321-9310 and a resistor. When one or both of these components shows signs of failure
cut out both components and reconnect the black wire with waterproof 14-16 gauge butt connector."

don't know if this does anything for you, but it's interesting

That is interesting, Honeyburst. What do they consider early models?

All the people I've talked to who have 5.0 Fox bodies say they have the old style sender with the extension tube. I'm going to try replacing what I have and see how it works.
