3 Way Fuel Valve – 1/4” NPT – Boat Fuel Systems – Marine Fuel System Parts 350990
3 Way Fuel Valve - 1/4” NPT
Control the selected tank supply with this Waterline brass three-way selector valve. Product 350990 uses 1/4 inch NPT connections.
The selector format is intended for switching between tanks in a dual-tank or main/reserve installation. Identify the intended tank routing before choosing the valve.
Match the stated thread to the existing connection and confirm the complete fuel-system application. Thread diameter, thread standard and hose connection size are separate details to check.
Choosing and using this product
Retain the part code and any compatible equipment references with the boat’s maintenance records. That makes later filter or hose replacements easier to identify. When several engines or tanks are involved, label spare parts so different connector styles are not confused.
Review the listed contents before planning the job. A connector, hose assembly, primer bulb and tank each cover a different part of the system. Determine which adjoining components are already present and which are expressly included with this product.
For this version, material: brass. Use that specific detail when comparing the item with your existing equipment or planned installation. Other sizes and configurations in the range should be checked separately rather than treated as equivalent.
For this version, thread: 1/4 inch NPT. Use that specific detail when comparing the item with your existing equipment or planned installation. Other sizes and configurations in the range should be checked separately rather than treated as equivalent.
Match the component to the fuel system and the exact connection being serviced. Hose size, thread form and engine-side or tank-side fitting style can differ between otherwise similar products. Use the stated model references rather than relying on a familiar connector shape.
For a tank, check the available space and access for filling, removal and hose routing. For a filter or replacement element, identify the existing assembly and its service requirements. A replacement element is different from a complete filter head and bowl.
