I am bringing back to life a long parked K75. Sure enough, the fuel pump damper turned to goo. I am replacing the ridiculously exhorbitant OEM fuel pump with a reasonably priced pump from the auto parts store. But I also hesitate to blow a wad of cash on a new rubber damper. I have searched here but have not found a replacement. Has anyone found a substitute, or else a way to fab something that will work?
