Does anyone know what the thread size is on the Throttle body for the fuel line and return fuel line?

I'm converting my 72 K20 to TBI and want to use Aeroquip's socketless tubing, but need to know what fittings to get, and they list them as NPT and AN. I know the threads are metric.

Thank you in advance.
