Archimedes Penta 50 fuel pump

[Flyingdragon_uk]

HI,<br /><br /> I'm hoping someone can help me, my bing fuel pump/filter is not pumping fuel in, on examination of it the gasket/diaphram has gone hard causeing it not to pump (i think), is there any bing pumps that would be ok to use or where can i get a new diaphram/gasket? or could i mod/make one?<br /><br /> Many Thanks,<br /> Graham.
