Upon purchase we will ask you to provide the location of the female threaded fittings, inlet, outlet and vent. Inlet and outlet are typically 1.5 inch diameter, but the vent size can vary: 1/2, 5/8 or 3/4 inch hose. Please let us know if you need a recess in the top center to accommodate the vent fitting.

You can use the attached sketch as the basis for a drawing.

Please take care and confirm the shape and dimensions will work for your boat. These tanks are not returnable.

After we receive your order a shipping quote will be provided. Tanks ship via truck and are less expensive to ship when delivered to a commercial address.
