[SEL] 22 hp stover fuel pump,, brass advice needed

[bill boyce]

i need to replace the plunger in fuel pump on the 22 hp stover due to wear. the plunger is of brass material and
travels in a cast iron bore of the pump body,,,,,,,, in checking some catalogues i found several different kinds of
brass alloy material,,,,, maybe one of you experts could suggest which type of brass would work best in this
application,,,,,, ?
thanks in advance for any help,
