After 18 months of searching I've found a replacement for the Kempax K504/5 pump made by Raritan.
The valves on mine had lost their flexibility and I couldn't find any to match and the exposed cover was brittle and ugly.
I found it after seeing a catalogue shot that looked similar. An email to SPX Sweden resulted in an email from the Customer Service Manager in Illinois that gave me the new model number of the old Kempax.
The Canadian distributor had no stock and I didn't want to wait 10-12 weeks so I found 1 in stock at Pump Vendor. They shipped quickly and now I have a Johnson 70-50005 Viking pump.
The only differences are longer inlet/outlet tubes for better clamping and black coloured plastic parts.

It this the manual pump? 18 months? I've never used the one on my boat it's in the transom don't even have a handle for it. Seems to it's made by Whale.. but I don't know really since I've never looked at it. I know the hand pump for the head tank is not working but I'd NEVER use it anyway.
