Quick Carburetor Fuel Inlet Question

[Simon T.]

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!

The issue is to get rid of the pressed in fuel inlet. They come loose and fall out. (mostly the little webers ).
Pull/twist the inlet with plyers gently. If it moves, take it out. The required fix is to tap the hole.
If you can't move it , run it and watch it on a regular basis for coming loose. IMHO.

The fuel line spec is open. Hose/clamps etc. all good.

It is as Mike described.

You do not need to replace with AN fittings.

the stock Nicki inlet is fine.

Awesome, thanks you all!
