Nice writeup in Road & Track Magazine

Thanks for that. I absolutely loved the subheading...
Like clockwork—just weirder and full of flammable liquid.

Michael, I got a kick out of “ it looks like Rube Goldberg's toaster.“

This is another gem ... or stinger:
Take the plungers. They run in steel barrels with micron-level clearance. No seals separate them from the oil in the pump's sump. Their fit alone holds back the 400 psi of fuel they can produce. All this for a marque where production inconsistencies mean body panels don't always fit when swapped between cars.

It dawned on me, Tyler, that not all of our non-USA friends, and even those USA members who might be either late or very late baby boomers, or even Gen X or Millenials, might not have a clue as to the Rube Goldberg reference--either the man (a cartoonist) or the wacky machines he "invented" in his cartoons.

Heath Robinson was Britain's equivalent, his cartoons were also amazingly complex.

For fun, here is a great music video inspired by Rube Goldberg .

OMG! Great vid! I wonder if that is what is going on inside that little case we call a fuel injection pump...>!?

Well, JonnyB, in a sense a carburetor does a very similar thing and many carburetors have very few moving parts and very few adjustments. So, in very real sense we do have a Rube Goldberg Machine inside our FI pumps.
While I was entertained by that video, I must say that it didn't appear as if every action triggered something else, it sure appeared as if there was a lot added (remember it's a music video!) just for visual effect. But, very well done indeed.

The FI pump was not manufactured by Daimler Benz.
It was made by Bosch.
During a time when that supplier still made high quality parts and did not have to compete with cheap Chinese imports.

DB and Bosch.....? ???

Mike,
read the article again, it deals with a SPICA pump for an Alfa Romeo. The ironic remark about the non-fitting panels refers to that marque not DB.
