I'm talking about this part. I did not split but in an effort to clean it the piston came out and so did the spring. I cannot find the spring.

I know this Thread was quite some time ago but I might have a likewise issue with the Kjet of my Porsche 928S of 1980 :
Car starts hard warm+cold when car is started after 1h or when engine is completely cold.
I can also always here a little squealing sound during the priming of my pump before the actual start...
Once started, and I cut engine after 5 secs and try to start again it always start properly.
Could the spring (or missing spring) on top of the plunger be the root cause ?
I have a FD with Bosch nr 0438 100 027
