tap for oil pan - 1/2"x13npt ok?
 

most of the guides call for 1/2"x14npt, but it just so happens that my tap and die kit has a 1/2"x13npt tap. I am guessing that 14npt in this case means 14 threads per inch? If so, and taking into account that the oil pan is so thin there will only be a couple of threads, would I get away with the 13 npt tap and it would just be a little more snug of a fit?

1/2-13 is NC (national Coarse) not NPT....it might not work....just test it on scrap metal first.

if you need the proper 1/2NPT let me know.

doh - thanks for the warning. I'll see if i can find what is called for at the local hardware store. definitely trying to do things right the first time round.

where you located? Maybe someone local has one, they are expensive if i remember correctly

1/2" pipe is WAYYYYY bigger than 1/2" bolts. thumb vs. pinky size.

habor frieght has one,

not too expensive either.

thanks guys - I am in sterling, va. (nova)
I am always up for ordering from harbor freight, since invariably more tools tag along for the ride. But I might check the hardware store first just to see what they want for the tap since I don't need the other stuff in the kit. Anyone know a good place to find the bit?

Oh and braineack, thanks for the tips on oil lines. I am ordering:

dude. then stop by my house saturday in CENTREVILLE and pick up the drill bit and tap you need. I'll be working on Newbsauce's ride installing a megasquirt and a bunch of other goodies....and you can point and laugh at mine.

thanks man I may just do that! can you PM me your phone number? what time will you be wrenching? and to respond in *edit* whoops I am thinking of rev2red's car - I don't think I have seen pics of yours? Really looking forward to seeing your setups though.

rev2red is braineack's boyfriend. they share the same car.

scott I want my sensor some day too.

rev2red = my vanity plate.

We'll probably be out early to avoid the heat, and work for a few hours.

By the time you come over my head will be removed....so it won't be very pleasant to look at :gay:
