Will a fuel pump for a 1955 truck with a 256 y-block fit and work on a 272 eng?  I am thinking of buying the pump pictured in this link.  It looks like the pump on my 272, which has failed.    https://www.ebay.com/itm/334060924645?mkevt=1&mkpid=0&emsid=e11304.m43.l44813&mkcid=7&ch=osgood&euid=d9c11f56aa39426   any help is appreciated.  thanks,  Jim.
