Explain "npt" to me (ie 1/8 npt, etc...)

Bobby,
I don't see any reason why the galvanized shouldn't work. I should be just fine.

The galvanized will work but isn't the best way to go,especially since nowadays a lot of pipe fittings are Chinese junk where the plating falls off easily. Best to go with brass or go to a tractor or hydraulic supply where you can get a fitting made of hydraulic grade steel.

Yes, that's the reason I don't want to use galvanized (the ones i found, anyway). They all looked like they had been hand carved by some 5 yr old (who knows, maybe they were... )

I don't think I'll have any trouble tapping, I've done it before, just never for pipe thread.

dmurdock,
Their advice is right on the money. I just did this job with a 1/8 npt using a 5/16 drill bit. It came out perfectly even though I had never tapped anything before. Take it slow and pay attention.

Just an update...

I got everything installed today... works great! Thanks to all who helped.

ps: I actually cussed more messing with the boost guage than the egt probe... drillin' and tappin' was probably the easiest out of all the different chores involved.
