You have s Coleman pump fitted , I think they were used to replace broken Westy ones. Westy ones have flat pump handles and push fit faucet pipes, Colemans have a ball handle and a bolted compression jointed faucet.
I did once find a nos faucet pipe on the Samba but I would just keep scanning the ads for a replacement unit.
