John,
I will look at the pump to see if I can find a Mdl number but when I did disassemble it to clean it up and see if I could find parts to rebuild it I did not find any tag nor do I remember seeing any Mdl number. But I will check again as maybe I just missed it or don&#039;t remember seeing the number. I will try to get back to you after I check this out. 
Do you have any leads on a head gasket for the 1450 with the Fiat engine along with any rebuild kits such as pistons, bearings, sleeves or other.
Thanks Richard
