I think these are right but don't quote me

1. is the black box on the side of the metering head near the crankcase vent pipe

2. on the sandwich plate for the injectors

3. I presune you mean the cold start injector if so on on the bottom of the inlet manifold (blue) will have a fuel pipe or fitting on it

4. this IS on the end of the inlet manifold near the brake servo and the connection is green

Hope this is of some help and some one please correct me if wrong
