By definition, the four Whitworth Thread Forms are:
BSW (British Standard Whitworth)
BSF (British Standard Fine)
BSPP (British Standard Pipe Parallel)
BSPT (British Standard Pipe Tapered)
Therefore, both pipe threads are in fact Whitworth since the criteria is
that they have a 55 degree angle on the threads versus a 60 degree angle of
other thread forms, e.g. UNF, UNC, SAE Fine and Coarse, BA, BSC, etc.
Other non Whitworth British threads include, BA (British Association) and
BSC (British Standard Cycle).
I hope this clears thing up for everyone.
Cheers,

Bob,
Fuel fittings are British Standard Pipe (tapered thread) or British Standard
Pipe Parallel (straight thread). I don't believe any Whitworth was used in
fuel lines or components.
