An fitting on primary fuel rail?
How am i supposed to do this???? I have all the fittings/hose and the adapters listed on fc3s-pro.com. But they are using a custom primary fuel rail, that is threaded.The stock rail has straigh nipples on it.The reason is i have an aermotive fpr, and a k2rd rail with 1600cc for the secondaries, i am using stock 550s for the primaries but i just want the fitting on there also.

From Teds site:
We are not aware of any aftermarket upgrades for the FC3S fuel rails. If you do come across with such a thing, please drop us a note! It is advantageous to convert 1989-1991 Kouki fuel rails to the earlier 1986-1988 Zenki fuel rails, because the later 1989-1991 Kouki fuel rails are one-piece design with a welded fuel pressure regulator. The 1986-1988 Zenki fuel rail needs to be custom fitted, since fuel rail position is a bit different.
Spec on the stock turbo FC3S Zenki fuel rails:
"Small" fittings are M12x1.25 - these are the pulsation damper/FPR ends - Solex/Dellorto carbs run the same thread pitch
"Large" fittings are M14x1.5 - these are the opposite banjo bolt ends
Most AN suppliers (Earls, Aeroquip, Russells, XRP) carry these metric size adapters to -6AN
