    After my last thread, I am looking to add the crossover between theWUR’s. Wondering if anyone can confirm the parts needed? After looking at Eurosspares this is what I have so far:

    113925. crossover pipe x1
    114018. Banjo bolts x2
    10260160. Washers x6 (maybe 4 if replaced with gaskets, but six are showing on the testarossa which uses the same banjo bolts.
    14330260 gaskets x2. Maybe as they are shown in the 412 schematic I guess would replace the upper two of the washers. (Or is it 6 of these?)

    Also does the crossover pipe attaches to the larger or smaller banjo bolts on the WUR’s?

    Any confirmation of the exact parts would be greatly appreciated. As this is all new to me. Hopefully she will be running better soon.

    You always put new washers or they may leak. You could anneal the copper and re-use the washers, but on such cheap parts, it's a waste of time.

    As you pile up 2 banjos on each WUR, you need 3 washers per WUR.

    All your shoping list is made by cohline and easy to source from cohpro.

    The crossover attaches to the control pressure line, i.e the line that gets out of the middle of the fuel distributor and goes to the WUR inlet. (I do not remember which has the bigger bolt...). This way it balances control pressure of the two k-jets.

    Hi Raemin. I was holding out to see if I could find the stock part instead of building it. Although of course much less expensive. It’s been hard to find. If I build through cohpro do you know the proper parts, banjos and fuel line etc? Thanks.
