There is a single company in Turkey that makes all the rebuild kits for 
the AC style mechanical pumps in the world.  They are built specifically 
to be Genuine Land Rover replacement parts for the AC fuel pump used on 
the four cylinder petrol Land Rovers.  The same rebuild kit minus the 
land rover box is sold to everyone else.  The kit services all the 
various flavours of the standard body AC mechanical fuel pump plus the 
look alike aftermarket replacement for the NLA Land Rover pump. My guess 
it if the company designed the pump to be a look alike replacement and 
it has a ring of bolts that it will be rebuildable with the standard 
rebuild kit.  You could find out in less than an hour by trying to 
rebuild one.

Early style AC pumps had the valves held into place with plate attached 
with a screw.  However later the GENUINE AC fuel pump used the crimp 
mounting method. What you are describing is the difference between the 
early AC pump and later production runs of the same pump.

If you were to look closely at diaphragm Illustrated the factory manual 
and compare it to the actual diaphragm you will see the the plates at 
the centre are reversed.  The folks in Turkey got it backwards.  The 
Land Rover folks made one attempt to get them to change the tooling so 
it assembles the part correctly but the Turkish company said it would 
cost too much, and besides it works OK assembled that way.

Bottom line is the kit is available from a single source world wide and 
that it works inspite of the diaphragm being assembled backwards.
