    Car is an '87 328 GTB. Slowly getting there on the rebuild and I'm now getting ready to replace all the plastic fuel lines that connect to the fuel distributor.

    For some damn reason, I did not map out the connections for. pipes from the WUR and the cold start injector. I have everything mapped out except for:
    • the three barbs on the fuel distributor labeled A, B and C in the pic; and
    • the large banjo on the WUR (labeled 1), the small banjo on the WUR (labeled 2) and the connection to the cold start injector (labeled 3).
    Can anyone help out by telling me what the mapping is from A, B and C to 1, 2 and 3 in this picture?

    Thanks.

    No worries. However, I notice that your injector port numbering is different to mine, and I'm a bit confused.

    On my car the rear bank injectors are fed from the 4 rear ports of the distributor, and the front bank injectors are fed from the front 4 ports. The pipes that I can see in your photo seem to agree with that layout, but the numbers you've stuck on the ports don't.

    The sequencing of the ports doesn't matter on the CIS system, they are all continuously fed from the same chamber inside the fuel distributor unlike electronically controlled sequenced fuel injection. That being said there is something to say about the esthetics of nicely organized fuel lines.
