Make an eco-friendly statement with the Attwood Fuel Vent Line Surge Protector by avoiding fuel spills! This innovative product acts both as a fuel line vent and a surge protector, eradicating the need for installing two different accessories. It effectively helps prevent vent line spills caused by tank sloshing and refueling. It features a simple surge-ball design that works on the inertia of surging fuel that drives the surge ball up against the upper seat, closing the large vent opening. The passage is restricted to smaller openings, which diminish fuel flow and lessen spillage.

Featuring a glass-filled polypropylene construction, this vent is tough and extremely durable when up against oil, gas and alcohol-blended fuels. In case of non-automatic nozzles, when the tank is full, the surge protector produces a gurgling sound to mark it. It functions at any orientation within 45° of vertical and meets the standards set by ABYC with aplomb!

Easy simple instructions, I believe it has solved my problem but too early to know for sure

I'm looking at this product for a vehicle application. Would this allow the gas tank to vent during refueling as well as help prevent fuel from leaking in the event of a rollover?
Attwood does NOT recommend using this product for vehicle application, and therefore cannot provide accurate performance expectations for use in a vehicle application.

Could this be mounted vertically above tank level but then hose would turn and drop before again rising to outlet?
Attwood confirms that it will be okay to mount this surge protector like this as long as it is vertical.

Would it stop gas from coming out vent hole on side of boat when stopping truck and gas tank full on boat?
Yes, this vent line is designed to prevent spills and leaks of all sorts.

With this installed in gas tank vent line would boat still pass coast guard inspection?
Yes. This product is Coast Guard approved, it would pass Coast Guard inspection under these circumstances.
