Injector hold down thread size/pitch

Hi All,
Does anyone know the thread size and pitch for a 12v injector hold down nut? I have to find or make a plug that threads into the hole so I can do a leakdown test on my motor.

Thanks,
Travis

Don't know the size offhand but it's the same as the wheel lug nuts.
Just take a lug nut off, take it to the bolt store and size it up.

Bill,
Thats the line nut size (14x1.50) I'm looking for the hold down nut/collar size. the one that holds the injector into the head.

Thanks,
Travis
