I recently purchased a 2003 Mainship 400. When we purchased the boat there was duct tape covering the fuel vents located on each side below the fill tubes....The tape was removed and all was good. When we started to fill the port tank there was an immediate "overfill" event causing diesel to flow from the vent tubes and out around the fuel nozzle. To make this long story short we found that if we slowed the flow from the fill nozzle to a slower flow mode the spill stopped although the vent tube did continue to drip very slowly. Same story on the starboard side. So here's the question......is this normal on a Mainship? Has anyone modified this vent to allow a high flow nozzle to work or is it just the way it is?
