My Ericson 25 came with a Fynspray WS 64 hand pump for the galley sink in unknown condition. Removal of the pump and disassembly revealed a pump in surprisingly excellent condition with one substantial exception. The gaskets are all pliable and there is no corrosion. But the plastic fitting that seals the lever arm is broken and needs to be replaced. I sourced a used unit in much rougher shape that has the part I need. My issue is I need to separate the brass arm from the chrome lever arm in order to remove the plastic piece I need to replace.
Is this simply an interference fit that can be hammered apart? Anybody know how? I contemplated heating the brass but didn't want to if there was some rubber or composite seal between the brass and Chrome. I can use the entire arm that's in rougher shape but I'd rather not. Attached are pictures of the existing arm and the replacement pump arm for reference.
I'm also surprised I haven't been able to Google search a solution. I thought these pumps were very common. I see how to replace the seals but that's not my issue - mine are great.
