I need a little help with the carter button top FP I pulled off my car 6S2227. I'm not sure how to date it or identity as the correct model for my car. I really find it hard to believe it is the original Fuel Pump - it had to be replaced over the years? Though prior to me purchasing the car in Feb 2019 - its been sitting since about 1982 ish. Main body displays 0-1719, then under housing one side has (hard to read) 4567S & other side 12F9A (maybe?) I hope it is the real deal but really do not think it will be. I searched the archives in this forum and didn't see any old postings for button tops. I appreciate your time- Fred
