It makes the whole job easy and you won't screw up either the case surface (that sees a very thin gasket) with screwdrivers.
I don't make up my own hoses. I get the lengths needed and just an inch or two longer, mark them as to the final length and orientation of end fittings and once it's all marked up I take everything to my NAPA store and they make them up.
