CIS-E3 Fuel Distributor & cold start injector port

[ben swann]

I've been installing NG engine with CIS-E3 fuel injection into '87 4000
quattro, and am now hooking up the fuel injection.

All the lines for the injectors had been disconnected from the fuel
distributor/metering head.  Now I'm screwing them back in again and am
trying to get them lined up pretty so lines dont cross, etc.

More importantly, is one of the ports on the metering head especially
for the cold start injector?  This distributor actually uses all 6 of
the fuel injector ports - shouldn't one be supplying system pressure
for cold start injector?

I did notice while cleaning, one of these ports seems to be deeper than
the others - pesumably that's for the C.S. injector, but I'm trying to
verify.
