The injectors worked fine when the Lucas pump was on. I’ve read elsewhere that when doing the conversion to a Bosch pump I can keep the Lucas Stanadyne pencil injectors. Is this incorrect or are you suggesting that my injectors are not working correctly?

I’m not moving to a Lucas, I removed it. Put a Bosch instead.

I looked in the interactive manual in French for the opening pressure of the "thick" injectors for the Bosch and Lucas CAB pumps; they are practically the same: 260 and 250 bar, respectively.
This is for new ones, old ones need to be checked and adjusted as close as possible to the nominal value for the BOSCH pump.
