I will outline the gasket on a piece of cardboard and insert the bolts in as I take them out as to not mix them up. I have all the necessary tools. I got a new Cardone pump for only $100. It came with a standard nylon gasket but also a rubber gasket of the same shape that's like a rubber band. Not sure what that is for? Those of you who replaced the pump please advise regarding the gasket and if anything tricky/anything I'm missing. Thanks.
