sorry to bring this up again. DC2, you said i need a 1/8 BSPT to 1/8 NPT, correct? i emailed autometer and they replied back saying i need a 1/8 NPT to 1/8 BSPT (part #2269) now i am all confused.
how do the BSPTs and the NPTs compare? does one have slightly larger threads on them? which one?

thanks,
Jon
