So the PO of my SL had the front/rear accumulators replaced just before I bought it, but I'm going to do the pulse damper because I'm starting to hear a faint chug/whine on startup for a second or two. I checked the fluid level and all is well there so I'm hoping the pump isn't on the way out. I'm guessing there shouldn't be much fluid loss when doing this repair?

Anywho, what I'm really trying to do is confirm the part #. I checked the spreadsheet of ABC components in here and it claims that 2203270215 is

 

part # is correct. You do not specify your model year but if like my '03 it is in fender well and may be in real tight. It is on a flexible mount making it sometimes hard to pull. I used a wood block between fender and pressure assembly to aid in tugging on it. If on the pump itself (later models) I hear it is a bit harder to release.

That's really odd, I've put in all that profile info several times now but it just won't stick :

My car is an 04, so it's the one in the front wheelwell. Thanks!
