You realize that a 3/8" NPT plug is over 1/2" in diameter right?

nope your way off i just looked the tap, you use a 5-16th drill to drill the hole

Actually, Tim is right. Pipe thread sizes are way bigger than the number marked would imply, 3/8 pipe thread is indeed bigger than half of an inch. Double check the tap, since the tap required a 5/16 drill bit I'd say it's closer to 1/8 pipe thread.

I *think* 3/8" NPT is 5/8-18 tapered thread.

I just bought this fitting from the dealer and it measures 7/16" on the fitting that presses into the housing.

3/8-16 amd 3/8 NPT are two totally different things. A 3/8-16 tap is NOT tapered thread. 3/8 NPT is a tapered thread that you could thread a 3/8" inside diameter pipe into. Thus why it's 5/8" or so in diameter.
You don't know what to tell me cause you didn't have a pipe thread tap in your hand. /forums/images/graemlins/waytogo.gif

the tap said exacally 3/8-16 NPT so if thats not NPT i dont know what it is i would take a picture but the writing is a little worn down and it wouldent show up in a picture. also the 3/8 npt barb fitting that i asked for at napa went right in so eaither way it worked and now i got to do the same thing to the 14ff but bigger

update***** i was way wrong!! between Tim and the Old- school guys over at Boeing I got schooled. i used a 3/8-16 NC tap on the 60. The hole size on the 14ff is 7/16th but there is no tap in NC for that hole size But they do make a NF tap for that size hole so ill se if i can find a fitting in that size
