I bought the OM603 OFV on greazzer's site and received the OFV as shown in the picture:



however after pulling the OFV on my 1987 300TD it appears the stock OFV on my car is quite a bit shorter:



Of course I still tried to install it even though I was pretty sure it wouldn't fit. You can see here there the new OFV bottoms out with a pretty big gap:



Assuming I'm installing it in the correct place on the pump is there any reason my pump would have smaller/shorter OFV than others?

I've previously purchased an OFV and injectors from Greazzer for my OM617 with great results, so I'm assuming my I'm either doing something wrong or have a different pump than other OM603 engines. Hoping someone might have some insight here.

thanks
