Lister H80A Water Pump

Does anyone know much about this model of water pump as I cannot find that much using google. The pump was connected to a Lister D engine originally but is now missing the air chamber (i think that would be the correct name)?? Any information would be appreciated or someone to contact regarding spares or where I could get an air chamber from.

This is actually a Lister H1 pump, you should be able to find much more about that out on the web.

Air chambers not available new (as far as I know) so a wanted ad on here, or regular ebay searches might find one (eventually).

Failing that you could attempt to make one using a suitable flange and a small gas cylinder.

Thanks for the information. Yes, I can find a lot more information on the H1. Do you know why the pump is stamped H80A if it's an H1.

It is not stamped H80A, that is the casting part number of the main pump body.

I have the part for the top of the H1 pump are you looking for one
