Fuel Line Valve Shut-Off and Selector Kits
Inboard Fuel Line Valve Kits
Along with good fuel lines, the right inboard valves are necessary for controlling the flow of gasoline. Valves can determine where the engine’s fuel supply is coming from and even cut it off as needed. Marine Parts Source stocks boat fuel valve components made by leading manufacturers like EVM, Moeller Marine Products and Whitecap Marine. Order them to replace a damaged valve or to update the setup of your vessel so the engine is always being fed.
Upgrade Boat Performance with High-Quality Fuel Valves
Ensuring proper fuel flow means a better, safer marine experience. A fuel line valve shut-off is essential to stop gas from reaching the engine so you can do maintenance or quickly react to an emergency. These valves come with several options, including 1/4" and 3/8” fuel line shut-off valve connectors. You can even use them to pair different line and fitting types.
We also carry an assortment of selector valves for boats with multiple fuel tanks. A fuel selector valve in marine applications lets you switch the supply from one tank to the other so you can keep on boating. Get a 3-way fuel valve for a boat with two tanks or a four-way selector valve if you have three fuel tanks. Look for these valves plus check valves, anti-siphon valves, sump valves and others.
The boat fuel valves sold at Marine Parts Source are made of materials like brass and aluminum that resist saltwater corrosion. Order them by noon CT and we’ll ship them the same business day. Call us toll-free at 866-388-0390 for assistance finding the right valves.
