The 1.5\" ports are spun closed at the factory so you only open the ones your plumbing actually uses. Open them with a hole saw on the bench, before the tank goes anywhere near the van, and vacuum the shavings out. Plastic chips inside a fresh water tank are a mistake you only make once.\u003c\/p\u003e\n\u003ch3\u003eDoes the tank need a vent?\u003c\/h3\u003e\n\u003cp\u003eYes. It is designed to run unpressurized. Run a vent line from the top 1.5\" port up above the maximum fill level and out through the floor or a body vent. Skip it and the tank will deform on a hot day, then pull its walls in when the pump runs.\u003c\/p\u003e\n\u003ch3\u003eHow much weight am I adding to the van?\u003c\/h3\u003e\n\u003cp\u003eWater weighs roughly 8.34 lb per gallon, so 28 gallons is about 234 lb of payload once full, on top of the dry weight of the tank. Put that number in your build budget before you order rather than after — it is the most commonly forgotten figure in a van conversion.\u003c\/p\u003e\n\u003ch3\u003eDoes this need the 3.5\" riser that the Sprinter tanks need?\u003c\/h3\u003e\n\u003cp\u003eNo. That note applies to Sprinter-profile tanks being fitted into a ProMaster.
