Fuel union size?

[Chug-A-Lug]

Me again...

Does anyone know the thread size of the fuel union on the cold start jet? Having refurbished the jet it now let's fuel by and I'd like to fit a tap without replacing the jet, but I'm rubbish at working out thread sizes.

Thanks for any help.

Hi Sam,

Sorry I can't help with size, but get a set of digital verniers (an oxymoron for sure) and a set of these:

Make sure they have metric and tpi sizes. You'll never regret it!

I measured it as an 1/8" BSP parrallel thread.
