attwoods probably has leathers. if you have the cyl out of the well,you need two big pipe wrenchs and take off the top cap and the bottom cap. yes it probably had a dip tube on the bottom of the cyl to get deeper into the well in case the level dropped. i would measure static water level then arrange the cyl five feet or more below that then put a new dip tube on the bottom around ten feet or so. once you have the caps off you can push the plunger out off the barrel of the pump and you will see the leathers. the foot valve is in the bottom cap. inspect the pump barrel for wear and deep gouges. if worn out replace with new barrel or just get a new pump. chances are it is ok though,these are very forgiving. when you replace the leathers put the whole pump into a buchet of water and soak for a few hours before working the pump. you can test it now and see how it works. use plenty of pipe dope on the joints when you assemble. next get a windmill.
