Does anyone know the thread size of the petrol tap??? There's hundreds of variants on Ebay that may possibly flow faster than the standard one, some are quite indiscreet like the original.

I had a look today Dave,and the pitch is 1mm but the tap is a taper fit.I tried an NPT 1/8 -27 die on the tap threads and it fitted perfectly but whether Innocenti used this size I'm not sure.

Hi Lloyd, thanks for that. I didn't realise they were tapered. Perhaps I'm being a bit paranoid about petrol flow? What do you reckon on the original tap and tuned engines? Cheers mate.
