Holley Systemax Thread Size AND A-N Fitting questions.

FIRST...on the Systemax, what is the tread fitting size?? It should be the same as the other intakes but I dont have the size right now...I know all the Autometer sending units thread right into them, but I need to order an after market fitting. (Reffering to the threads where the Water Temp sending unit goes.



ALSO...If I want to replace a 3/4" inside Diameter water hose with a Steel braided hose, do you know what the A-N size equivalent will be?? Im guessing 12?

Thanks

Well nevermind on the A-N question...each A-N nuber is 1/16"....So an A-N 4 is 1/4" (4/16), an 8 is 1/2" (8/16) etc, so then yes to my question...12 is 3/4"!
