Hello everyone.
First of all, thank all of you who contribute to this forum your experiences and technical data, the truth is that it is being of great help for the restoration of my 230sl 64. I bought the car disassembled from an acquaintance and I find that I have a injection pump of a 250sl, ref PES 70A 120 R18. I think the best option would be to change the pump, I'll do it later, but I would like to leave the car running with this pump. It fits well, the only thing is that the fuel inlet and outlet come from the front and not from behind. The pump connections are those that correspond to the R11, so the outlet pipe touches me with the fuel damper.
My question is...
Is it possible to get the overflow valve in the photo?
What do you think about mounting the R18 pump on a 230SL?
-
The overflow valve regulates the fuel pressure in the system. As long as you keep the fuel pressure above 11 psi. and less than 17 psi. it should work.

Hello Ivan
This reminds me of my situation with my 250 SL Pagoda. Instead of the R 18 it was mounted the R24Y. So, I have more or less similar experience.
If you are not restoring the pagoda to concourse level, leave the R 18 and enjoy it. Each next pump model has had some improvements,
so the R18 is for sure better than the R11?
The R11's pumps are very, very hard to get and you have to expect to spend at least 3.000 Euros for a restored one.
If you need a R11 write me a PM - my mechanic should have at least one on the shelf.
Greetings!
Sebastian
