There's a good explanation of basic Fuel Injection parts and what they do
at the bottom of this page http://www.type2.com/bartnik/tech1.htm

Scroll to the bottom --- you'll probably want to get sidetracked by all the
other
great info above the Fuel Injection info --- there's also a link to a scanned
Bosch FI Manual.
