1940 Radiator cap

    Does anyone here know if the radiator cap on a 1940 should be a "Filler cap" or a "Pressure cap"?

    Once the car warms up, I have water flowing slowly out of the overflow tube. The heat gauge reads OK but water continues to flow out. The cap now on it doesn't have the spring and seal on the bottom of it, so i don't think its reaching the seat.

    Anyone have a Napa Auto store part number? :D

    Thanks redron
