IN-LINE FUEL OVERFLOW DVC

The Attwood 1675-6 is a fuel vent line surge protector designed to prevent refueling spills. It works by causing automatic fuel nozzles to shut off as the tank fills. For non-automatic nozzles, it emits a gurgling sound to indicate a full tank. This surge protector incorporates a ball-style check valve with internal baffling.

Constructed from glass-filled polypropylene, it meets ABYC Standard H-24. The protector is designed for in-line installation with traditional tank vent systems using standard 5/8" ID vent hose. Its compact size allows operation in any orientation within 45° of vertical and it withstands oil, gas, and alcohol-blended fuels. The unit includes two hose clamps for installation.
