Here we have one of the quite rare small Autovacs, the tank is 3 inches diameter and about 6 inches tall.It is in perfect working order and I have just replaced it with a bigger Autovac on my car because I live in a very hilly area and the little tank doesn't hold enough fuel to get all the way up the longest hills without stopping or lifting of..
Early FIAT bronze water pump. I'm not sure what model it's for, possibly a 510? or possibly veteran? I know it's not 501.I can send more photos on request, and I accept PayPal.
