Pneumatic Pumps

Bosch R7

PRODUCED FROM 1957-1958
MODEL: W189 300d "ADENAUER"

This R7 comes from a later years of the W189, made specifically for the 300d Adenauer, making it one of the more sought-after and harder to find models of fuel injection pumps. Similar examples have auctioned for up to $30K dollars, so it makes sense to do everything possible to bring one back to life. 

The R7, being a later model of pneumatic governor pumps, features the bleached leather diaphragm visible on our pneumatic governor page, as well as various upgrades that increased efficiency and dependability. 

At the bottom of the page you can see how we go about testing this fuel injection pump to ensure the calibration is
on target and will produce ideal performance.
