Boating Basics: Before Going Out on Your Vessel

Fueling a Vessel

Never fuel at night unless it is an emergency. If you must refuel after dark, use only electric lights. Try to refuel away from the water or on a commercial fueling ramp.

Before beginning to fuel:

• Check the entire fuel system for leaks. Tighten connections frequently—engine vibration can loosen them.
• Turn off all engines and electrical equipment; shut off all fuel valves; and close all windows, doors, and openings.
• Do not allow anyone to smoke or strike a match.
• Always remove portable tanks from the vessel.

The most important safe fueling practice ...
If your vessel is equipped with a power ventilation system, turn it on for at least four minutes after fueling and before starting your engine to remove gas vapors.

• While filling the fuel tank:
  • Touch the fuel pipe or tank with the spout to prevent buildup of static electricity.
  • Avoid spilling fuel into the boat’s bilge or in the water.
  • Never fill a tank to the brim—leave room for gas to expand.
• After fueling:
  • Immediately wipe up any spilled fuel. Air out the rag after using it; never throw it in the vessel or the water.
  • Store fuel on board in a safety-approved storage tank, away from the engine and in an area of good ventilation.
• Additional safety procedures for PWCs:
  • Avoid spills when fueling in or near the water.
  • After fueling, open the door of the engine compartment and sniff to check for any evidence of gas fumes. Do this before starting the engine. If you do smell gas fumes, find the source and make repairs immediately.
  • Do not tip the PWC to “fill all the way up.” The tank provides for fuel expansion; if tank is overfilled, the fuel may expand and spill into the water.
