Checklist Before You Install

  • Cross check the Spec Sheet and the Install Instructions from the maufacturer of your bulkhead before you begin
  • Make sure you have your neccessary tools handy
    • Drill
    • Appropriate diameter hole saw
    • Grease Pencil or Marker
    • Scrap plastic or wood for testing your hole
    • Crescent Wrench
  • Ensure your tank is in good condition and is compatible with your new bulkhead
  • Drain the tank below the fitting location
  • Check your bulkhead for any defects or missing pieces
  1. Drain the tank and mark the appropriate center point on the outside of the tank
  2. Cut a hole in your test / scrap piece and ensure proper fit of the tank adapter. The bulkhead should pass into the hole but have no more than a 1/16th inch of side-to-side play. Proper diameter is determined by measuring the outside thread diameter of the fitting body and checking the manufacturer specification sheets.
  3. Once you are sure about the hole size, drill the hole in the tank and put the bulkhead (including the gasket) through from the inside of the tank
  4. Hand tighten the nut from the outside and be sure, if you have installed a siphon tube, that it is facing the correct way.
  5. Due to expansion and contraction of the tank walls, it is best to us flexible connections between tank fitting and rigid pipe or pump.
  6. Water test your tank to check for leaks.
