Engine Hours

Fuel Level According to Garmin

Everything off

Engine off

All AC circuits OFF

Diesel heater OFF (button at power panel)

Only necessary (lighting, water pump) DC circuits on

Overkill best practice would be to turn all battery banks off, but this is probably overkill...



Rags for any spill handy

Begin to fill based on the Garmin "fuel level" reading. The tank is 180 gallons. As you approach what would be 180 gallons, watch and listen for the tank to get full (and pay attention to any "auto stop," though not all marinas have these. Remember that based on diesel heater usage, the tank may take more than the Garmin indicates it should (1-5 gallons more). The goal is to completely fill the tank

Always watch the fuel vent for spills. If fuel is coming out of the vent, consider the tank FULL.

For large fills or if you are uncertain about fuel level, the tank can be visually inspected. It is located under the hatch in the cabin, immediately inside the door, which is usually covered by the cabin carpet.
