Mechanical fuel pump install

anyone wanna walk me through the installation of a mechanical fuel pump on my 318 in my 74 dart. I’ve never done one. Also do I need the 180 piece of steel hose coming off the fuel pump or can I just install a barn and use all rubber hose? Thanks. Using rubber as my steel line is in rough shape.
