Among the spares I got when buying my '50 was a never run rebuilt AC mechanical fuel/vacuum pump. Where on the pump did AC put the part number and how can I identify that it has diaphrams compatible with 10% ethanol laced gasoline? I already put the pump on the car and am having second thoughts about using it and thinking of using a Holley "Red" electric pump I have instead.
Thanks,
Bob

 

Go the info from the AACA site. the pump is a KEM remanufacture and has "Bunalon" parts which is a brand name for butyl nitrate rubber which can be used with todays gas with 10% ethanol.
