Have you checked the oil clearances, the gear/rotor end float
should be .002″to.004″ of an inch. The gear/rotor to body
clearance should be .004″to.010″ max. New pumps are expensive
but you can have your old one rebuilt. At the moment I have
7 Feltham engines in rebuild, two for Hans Natens of Belguim.

pump heavy scratches in the body and play in the gears
I am interested in retrofitting a pump if possible
how should I do?
I have received proposals for new pumps. providers indicate a flow and a higher pressure.
there are changes to the cannaux grease, body oil filter

there is a change on the camshaft but I do not understand
if you are interested in these changes sent me an email directly I will pass them on.ray sherratt14 November 2013 at 21:45 #50533
There is work on the block to reduce the unwanted back presure which destroys the scew gear drive. The face
that the pump bolts to needs to be opened to match the
exit opening the oil pump. The hole needs to be milled to
the depth of the transfer port below, preferabley with
a bull nosed cutter, or blended with a die grinder. Next
the transfer holes forward, and the two to the oil filter
tower, all need to be bored/drilled to 14mm. Be careful
on braking through into the the transfer drilling, not to
touch the oil presure relief valve port oposite. Next the
oil pump tower needs the same tretment. These operations
will require tapping for larger end plugs. The oil filter lower
and upper holes at 90deg to the vertical holes, need to be checked to make sure they line up to the block and the
filter housing. Make sure the gaskets don`t mask the
drillings. Last of all if you have the old rotary oil filter
copper screen type they can be coverted to a modern
