This Seachoice 90° Flush Mount Fuel Vent provides a fuel system with efficient ventilation, and its design minimizes its susceptibility to damage. Plus, the flush-mount design presents a clean, finished look. Made of 316 corrosion-resistant Stainless Steel, this Fuel Vent does not have a protruding cap as so many vents do, so it is less prone to cause damage or to be damaged by impacts. The cap on this vent unscrews with a hex head wrench for easy cleaning of the filter, and to accommodate pressure testing of the entire fuel system. This Fuel Vent requires a 1 3/8-inch hole, can be used with a maximum hull thickness of up to 7/8-inch, and it is designed to connect with 5/8-inch interior diameter hose. Seachoice is committed to delivering quality marine accessories and OEM replacement parts to satisfy fishing, boating and watersports enthusiasts worldwide. Seachoice is run for and by boaters, offering a wide-ranging product line while remaining affordable.
