Power Steering pump Issues

I need to replace the steering pump on my 06 230 but I'm having an issue finding the right pump. Every where I look they say these two pumps will fit but in don't 100% believe because the reservoir fittings are slightly different. Anyone with experience with this?? I'd hate to put the wrong pump on and find out it leaks!

I checked the info on 'rockauto' i assume this is the website?

96344 - Alternate/OEM Part Number(s): 54661601
965491 - Alternate/OEM Part Number(s): 44667801, 44667901

so from this i would say they are different (i'd expect to see the same alternate oem numbers) * or atleast reference each other

the info also differs.. one has a 'pipe' .. the other a 'hose' .. one is 'threaded' and one is a 'fitting' , more confusion!

How many litres is your engine? theres a few versions of your model - sorry, you have a 240, only 1 size, ignore that

Ive checked on a german website and it recomends this for your model https://www.autodoc.co.uk/ridex/8100015

this site says its oem part number is 004 466 78 01

i trust autodoc

so if this was who wants to be a millionaire, and i was your phone a friend. but you had just used 50/50 i would say "965491" FINAL ANSWER!

https://www.autodoc.co.uk/car-parts/oem/0044667801



54661601 is not for your car. again.. final answer!!

ok well according to the info the 'fitting' is not compatable.. i guess you have a different pipe specific to that pump.. maybe it was replaced along with the pipes at some point?

example : https://www.ebay.com/itm/Power-Steer...wAAOSwbwBfvqx-

can you confirm, do you have a 230 or 240 (your profile says 240)
i've been using 240 to seek lol in the words of Joe Biden "..come on man!" my brain needs a rest

Sorry for the late reply, been elbow deep under the hood last couple days. From what I can tell the only difference in the pumps is just the metal tip which I discovered is removable with a hammer and flat head screwdriver. The real factor to which pump to use is the reservoir. If the reservoir p/n ends with 09 83 then you use the pump without the metal tip. If the p/n ends with 23 83 then you use the pump with the metal tip.
