Default Fuel Rail Nut Size?

Does anyone know the size and pitch of the stock fuel rail "cap nut" located in the front of the rail. I'm looking to add a pressure gauge and I want to offset it slightly.

I'll also buy the 45's supplied with the LR kit if someone has them leftover.

Thanks.

Take the stock cap, drill and tap to desired fitting size. Either 1/8" NPT or -4AN

You cannot drill and tap the fuel rail test port cap, period. The ball under the cap creates the seal. Look at the fitting with the cap removed. This is a "globe seal" fitting. Fittings are available from

http://www.batinc.net/

Try and rig up something other than the correct fitting you'll risk a burndown.
