Fill it to the Brim
Anyone can spill a little now and then. but when fuel overflows, it's not only harmful to the environment, it's against the law. With a new deck-mounted fuel fitting from Securefill, you can clean up your act. I installed one on a Mainship 30 and was pleased to see that it worked as advertised.
Installation was pretty straightforward and took about two hours. I mounted it close to the existing fuel fill. Then I moved over to the gas dock to see how well it would work. When filling, you have to run a supplied clear vinyl hose from a quick-disconnect fitting in the unit into the tank fill neck. We took on 75 gallons and as the tank filled, the fuel that would have spilled all over the deck showed up in the vinyl hose-the signal that we were almost full.
I was concerned about maintaining sufficient airflow to the tank to prevent a vacuum while underway because I had to cut the original vent hose and join it to the Securefill unit. But a second vent line goes from the unit to the existing through-hull vent fitting, thereby ensuring the tank's equalized air pressure. Securefill is available in two sizes-one for normal gas/diesel filling and a larger one for those boats that use high-speed fueling systems.
