I'm getting my IT7 car ready to race and reading through the GCR again to double check things and see if anything major changed since last year. My car has a logbook, but hasn't had an annual done since 2007.

I just want to double check this mentioning:

9.3.13. CARBURETOR FUEL INLET FITTING
On all carburetors, (except SU, C and D Sports Racing cars with motorcy-cle-type carburetors and Formula 500 Mikuni VM38) with a non-threaded fuel inlet fitting, the fitting shall be replaced by drilling and tapping the carburetor body for a threaded fitting.

Am I right in thinking this means I need AN type fittings? Thanks!
