UPS/USPS/FedEx, take your pick. Bosch shop doesn't have to be in your area, you just have to be willing to pay shipping. USPS will be least expensive, if the shop is willing.

I wish I could find that thread again. Basically it was someone bought the part number everyone was listing but they were too big, so he tried some that he had from a different car and they fit and that was the part number I listed. I wouldn't be surprised if it was a California/Federal issue.

Also, I get the "any Bosch shop..." and all that, but I don't think it's unreasonable to be looking around for a cheap and easy source to get them that doesn't involve the inevitable $20 shipping for a $1 part.

I guess I'm probably too used to VW where everything is documented, factory service manuals are a dime a dozen, and they really never changed most of the parts anyway. These cars are like everything is a big secret, they kind of used the same parts except in California and between the years 1980 and 1981.5, and even if you find the part number it's been superseded by a new, more secret part number and if you call Mercedes they'll hang up on you. Then there's the "you have this pump so it uses these" and then someone else comes along and says "no no no, you have that pump and it uses these other ones..." and nobody seems to actually know, they just like to argue. AAAAAAH!

So forgive me for trying to do some digging, I just like to get to the bottom of everything I've ever wondered.

true...but easy to solve...just establish if you have a MW or M pump
first letters are PES5M or PES5MW .... delivery valves are not same hence the
dimensions of washers too.

to be true: MW delivery valve can not be used in M pump but M pumps valves can be plunged in MW but not advised as those do not have proper diameter.

cheers

I certainly understand that, but this whole thing could have been solved with a five minute phone call. USPS shipping is ~$7, and even UPS in a padded envelope would be quite inexpensive.

I recommend getting several spare washers, considering the cost of the part itself vs. shipping and hassle.

I get that, I just mean that people on this board span the globe and there are many Euro models in the US, so it's not always clear what everyone is talking about. And now maybe the California model is yet another difference to add to the mix?

I did find that thread I was reading through:

Where to buy OM617 IP Valve Delivery Seals

Interesting to me is the fact that he called the shop, gave them the pump numbers, and still got the wrong ones. That's another reason I like the approach of "X pump takes these, Y pump takes those, confirm the dimensions when you order them from the place of your choice."
