NO! BSP and NPT do NOT have the same Threads per Inch. The BSP
1/8" for example, as 29 threads per inch instead of the 28 that
an NPT would have. I don't have the Machinists Handbook at hand,
but will reply later with exact info. Using the Earl's catalog
is the next best thing, though. I think that the English just
went one thread off to confuse us over here.JMHO

Brian has it right, BSP (I believe stands for British Standard
Pipe) and NPT
(National Pipe Threads) have the same threads per inch and are
both tapered
threads (as all pipe threads are). The NPT seals on the tapered
thread,
whereas the BSP seals on a flange. Can you mix them? I have
on my MGB with
great success. Earls and Aeroquip fitting that convert pipe
threads to AN
should do the job. Use lots of teflon tape and tighten joints
well.
It's also highly recomended that you get an Earl's or Aeroquip
catalog and
explore your options. The mfg's catalogs show much more product
than say a
Summet or other sale catalog.
