Wow, Dave!

Where have you got this one? That looks really good. Although I am not expert enough to know what all the numbers mean. I.e. only a really experienced Bosch fuel injection pump expert will be able to do and adjust something with these numbers/specs on our pumps.

Give me a few days, I will translate it as far as I can.

Great work Dave<
Thanks for sharring it! Very hard to come by.

Hello Achim!
Hope all is well with you. Anxiously waiting your translation, although I have no idea of what to do with it!

Hey, that's pretty cool.  I can tell you this much so far: the first set of data refers to measurement points "b", "d", "g", etc., which presumably are denoted on a pump diagram.  Do you have the diagram?

Hi Gents,

Interesting information--my friend here in Michigan is a Bosch engineer (they have over 1,000 engineers in the Detroit area)and he tells me that the FI pump as fitted to our cars is from an old-line diesel company called Kugelfischer.  Bosch bought the company and their plant in Munich (?) many years ago.  Our pump is a derivative of a Kugelfischer diesel injection pump.  Recently Bosch was planning on closing the old plant where our pumps were made but some local labor issues forced them to keep it open.

I cannot verify this historical tidbit, but a German-trained mechanic once told me the Fuel Injection system for our cars was actually a variation of the kind used in WW II-era German airplanes to endure twists and turns up in the sky.

......yes James the German planes used fuel injection to overcome the problems that a carb fed plane would encounter when taking a dive, i.e when the plane is descending very fast the atmospheric pressure changes mean the air cant draw fuel through the jets and the carbs are starved of fuel so when you want to pull out of a dive ...........you hit the ground !!
