power steering pump

[BLACKMARAUDER04]

Now my power steering pump is leaking....

I see 2 part numbers

3W3Z17A385AAA is Marauder specific


7W1Z3A674A says 2003-11 Crown Victoria

Motorcraft lists it like this: Alternate/OEM Part Number(s): 7W1Z3A674A, 8W7Z3A674B, STP202

Is there a difference in these part numbers.

Ebay is offering the 7W1Z3A674A New OEM Power Steering Pump 2003 - 2011 Ford Crown Victoria Lincoln Town Car for $60

or Ford Motorcraft Power Steering Pump STP-238 8W7Z-3A674-B Automotive Parts FOR $155 including freight, no core charge

others are $200+ $70 core

Bump......

Can anyone tell me the difference between the 2?

I've used the CV pump from Ford on a Marauder. Couldn't tell any difference in drivability. They were physically the same. Only thing I can think of is that the MM one may have a higher internal pressure cutout setting or a higher flow volume than the CV one.

So I purchased 7W1Z3A674A says 2003-11 Crown Victoria
for $50 off Ebay. Came brand new in a plain open box.

It is a direct replacement and fits perfectly.
