Q1: What could cause the appearance of fuel in the below deck areas of a 2013 315 CONQUEST?

Q2: is the appearance of fuel in the below deck areas of a c.2013 315 CONQUEST a common occurrence?

Q3: what is a remedy to stop the appearance of fuel in the below deck areas of a 2013 315 CONQUEST?

The fuel in the below deck areas of a 2013 315 CONQUEST appears to be coming from a limber hole below the fuel tank and behind the boat batteries.

ASIDE: I cannot locate diagrams [that show] what structure the fuel tank sits on.

To access the fuel tank area under the deck is difficult.

Below are hyperlinks to diagrams from the website Whaler.com

The tank sits in a finished and gel-coated cavity.

Check the fuel fill hose, the fuel vent hose, the fuel supply hoses, and the fuel filters.

Report back.

Any element of the fuel system that is leaking fuel could cause the appearance of fuel in the below deck areas of any Boston Whaler boat with an internal, below-deck fuel tank.

ASIDE: there are no bilge spaces in a Boston Whaler boat. In a Boston Whaler Unibond hull boat, the area of the hull which would normally be a bilge space is completely filled with foam and sealed. The foam is continuously bonded to both the hull and the hull liner, forming a single structure--the Unibond hull.

A Boston Whaler boat will typically have areas below the deck level that are designed to be sump areas and intended to collect water that drains into the below deck spaces, often with a drain through the hull bottom and in some cases a lift pump that will move the water upward and overboard.
