Vintage car buffs may scoff at modern technology like fuel injection, but the truth of the matter is that fuel injection has been around nearly as long as the venerable carburetor. Experiments in fuel injection began early in the 1900s, and the technology became available on commercial diesel engin…

Minor additions to this great write-up:

  1. For future reliability, change all fuel lines to braided stainless Teflon lined hose. It is impervious to virtually all fuels including ethanol. Most stainless hose is rubber lined, so be careful. Get rid of that rubber if you are going to used pump gas.

  2. Don't be scared to tune mechanical injection with a wide band set up. If possible, check every cylinder separately. You can change injector size to match flow rates to individual cylinders. The aircraft industry has been doing this for years.

Thanks again MM for the great article!

i thought this thread was gonna be about USA HILBORN fuel injection, came out around 1949-50, before Mercedes 300sl, but wiki says some german engines used it in the early 1930S, or earlier!

are we talking port injection or direct chamber injection?

more info about fuel injection, little known fact is Electronic fuel injection was pioneered and patented by a USA company,BENDIX corp. i actually drove a 1957 AMC Rambler REBEL with efi in 1957, it was fairly good(not perfect), but Transistor technology was in its infancy!

and BOSCH thought well of it and bought license and patent rights from Bendix.

thats just KOOL.

Very important for early FI cars is to use non-ethanol gas too.  Pure-gas.org.
