Thanks for the info. I sent the metal top pump to Now and Then for rebuilding, it was working fine since I bought the truck, but has since failed. I have 2 more e-bay pumps on the way one is 1523089 and the other is 429 AF. Both glass bowl. I plan to get the best one of those rebuilt and put a glass bowl pump on the truck and keep the metal top for a spare. So it looks like the 1523089 will fit and not sure about the 429
I appreciate all the info and help
Sam
