Yes, he's right.

But you just want the tap size of the shcraeder valve.
Don't quote me but it is an NPT thread. It could be 1/4" NPT or a metric equivalent.

Cmon, after you bleed the fuel pressure it takes like two minutes to unthread it, you don't even have to pull the intake as youcan see it. With a long extension (1/4" drive) and a deep socket you can have it off quick. Then just take it to ACE Hardware and you'll have the fitting. You are looking for an A/N fitting, sort of a conical shaped head.

This is EXACTLY the same fitting used to fit into the turbo bearing section for the oil feed when you use braided steel line.
I've got an earls fitting downstairs right now but I'm too lazy to go and get it, snap a picture, etc. Maybe someone will link to a picture but I'm sure if he wants nitrous bad enough he'll do the little bit of legwork that is left.
