The plunger in the Bosch pumps is subtly different depending on the direction of rotation. If it wasn't then it would be possible for the engine to run backwards with very out of whack timing and lots of smoke. An old lister petter engined dumper at work would do this with a suitable reverse bump start. But the injection system on that was prehistoric.
The following was something that I cut and pasted yonks ago. With it you should be able to work out whether it will be ok. Apologies to whoever should get the credit! :wink:

c. x: number of cylinders
d. x: plunger diameter in millimeters
e. F: mechanical governor
f. xxxx: governor-controlled RPM number
