...I can not correctly identify this early Bosch MFI pump but I can see the body of the pump to be the same one as used to build the 911 RSR MFI pump. If you have one, I'll buy it! ajserrano@msn.com ;)
According to the late Paul Frere, application is a long tail 907 as used at Le Mans in 1967 with 2.0 Liter engine type 901/21. Due to space constraints, the pump was mounted transversely, and was driven by a pair of bevel gears from the usual cam/belt arrangement.
