Diesel tank vents

Diesel tank vents, preventing Diesel on deck.

This is what we did to avoid the Diesel vents to contaminate the deck while filling the tanks. We installed one "Racor Lifeguard Fuel / Air Separator" on each tank vent. This completely took away the annoyance of getting Diesel on deck through the vents.

Before we put the "Separators" in , we had the problem that it started to come out Diesel through the vents long before it was truly full, especially at high flow filling stations. We are no longer worried to fill the tanks fast. Just very nice to never have to be worried about it, and never have to clean up around the vents.

True, if you keep filling after it's been gurgling for a while, and continue, it eventually overfill at the fill hole. So it's now user-friendly, but not fool-proof. If anyone has a fool-friendly solution, please let us know :-)

The Outbound vent system

Is a smart system for Diesel tank venting. The tanks are vented through one of the lifeline stanchions on each side of the boat. This is to get the vent high and avoid getting seawater into the tanks. The system is made with the vent [right picture] going up into the middle of the stanchion. in addition, the stanchion has it's own vent high up. So even if there's water coming into the stanchion vent, it's highly unlikely that it will com into the tank vent inside.

The stanchion has drain holes at the bottom, to let any water and/or Diesel be able to escape.

This is where the Diesel spill is coming out [left picture].
