Ahoy matey! Based on yer request fer a Mitsubishi Canter 4D30 water pump, here be a couple 'o options from me PriceCheck search that might suit ye: The Water Pump Pressure Booster Kit 0.37KW Fer Jojo Tanks 220V looks primed fer increasing water pressure. While it be nay a direct match, this pump kit could help get more power from whatever pump ye install. Arrr. Also, the Water Pump Pliers 400MM be a handy tool fer installing or repairing yer pump. They'll keep yer fingers safe as ye twist and turn. Wish I had more direct matches, but me ships be still stocking me full catalogue. Hope one 'o these ideas be 'o help all the same! Let me know if'n ye be needin' anything else aboard me trusty vessel.
