Most of the line between the fuel pump and the bulkhead fitting on the engine compartment is hard plastic.  The connecting rubber hose between the fuel pump and the hard plastic needed replacement when I put the new fuel pump in.  I used two screw clamps to hold the new rubber to the hard plastic.  Is this enough given that the hard plastic is not flared and there is no ferrule?
