Hi, I have a 1986 190D with the 2.5 liter engine... previous thread suggested that it is a OM603 engine. Couple quick questions:

1. Where is the engine number located? Doesn't appear to be on the passenger side of the block, unfortunately, where it would be easy to see. On the block under the injectors on the driver (US driver) side?

2. Curious about whether the fuel system has a priming pump? My 240D has a very obvious priming pump down low on the driver side wheel well. I haven't spotted the OM603 one yet... suggestions about where to look?

Thanks for any help. I'm loving this car now that I have got the front brakes replaced! Really nice ride.

Kurt
