I raced a Fiesta from 1988-1995 and i also owned a 3 Capris before that and I used the 90 deg. addaptor to bolt on my Weber to the Fiesta manifold. I used the 1974 version but took a mill to it and machined off most of the extra bosses and material that wasn't needed. Then used some epoxy to fill the gaps left and to built a divider inside the addaptor to split the air flow to match the stock Fiesta intake flange. The Capri addaptor is open so you should do something to smooth the airflow into the manifold. Never any fuel starvation in the turns.

As for floats I have used the plastic ones as well as the brass ones. Never had a problem with either. Where are the brass ones breaking? How are you setting the float level?
