Hi guys im planning on installing a seaflow deck wash its specs say its  max amp draw is 12A    and its  fuse  is 18A. Should i still run an inline 18A fuse between the positive battery terminal and the pump?  there is no inline fuse on the positive wire of the pump (i presume the 18A fuse it has is internal). Im planning on running it to its own basic toggle on/off switch installed near the pump  (not through the main boat dash switch panel)  cheers for any advice
