AN Fitting sanity Check
I am looking to replace the heater hoses with braided line and AN fittings. The line from the intake manifild is 5/8" if I understand correctly this would be an -10. The 3/4" would be an -12. Also I believe that the NPT fititng that goes into the manifold and water pump are both 1/2" dose that sound correct?

Hard to verify this stuff when you are slacking at work

-2 hose has an I.D. of 1/8"
a -3 hose has an I.D. of 3/16"
a -4 hose has an I.D. of 1/4"
a -5 hose has an I.D. of 5/16"
a -6 hose has an I.D. of 3/8"
a -8 hose has an I.D. of 1/2"
a -10 hose has an I.D. of 5/8"
a -12 hose has an I.D. of 3/4"
a -16 hose has an I.D. of 1"
a -20 hose has an I.D. of 1 1/4"
And there you go. As you suspect, the pipe threads in the intake and water pump are 1/2 NPT.
