About this product
Help prevent fuel from flowing back through your boat’s fuel line with this inline non-return valve. It allows flow in one direction, helping reduce drain-back when the fuel supply stops. Available in three hose sizes, the valve fits into a compatible flexible fuel line. Choose the correct connection size to match your existing hose and installation. Product details Type: Inline fuel non-return / check valve Function: One-way fuel flow control Installation: Inline with compatible fuel hose Hose size options: 8 mm, 10 mm or 12 mm Pack quantity: One valve in the selected size Size and reference chart Reference Hose internal diameter GS31003 8 mm GS31004 10 mm GS31005 12 mm Check suitability Match the valve connection size to your fuel hose’s internal diameter before ordering.
