The (100) VALVE FUEL SHUT OFF - B is a marine-grade fuel shut-off valve engineered for positive fuel system isolation. In marine and performance applications, a reliable fuel shut-off valve is essential for safety, maintenance, and system serviceability.

Manufactured from corrosion-resistant materials with a positive-seal ball valve mechanism, this shut-off valve provides reliable fuel flow control. The valve is rated for use with gasoline, diesel, ethanol blends, and methanol. Female NPT threads on both ends allow direct installation into fuel lines. The valve body is designed for full flow with minimal pressure drop, ensuring your fuel system delivers the volume your engine demands. The quarter-turn actuation provides positive open and closed positions with tactile feedback.

A fuel shut-off valve should be installed in an accessible location between the fuel tank and the fuel pump. Use thread sealant compatible with your fuel type during installation. This valve meets marine and automotive safety standards for fuel system components. Regular inspection of the valve and connections is recommended as part of your maintenance routine. The corrosion-resistant construction ensures long service life in harsh environments including marine and off-road applications.

Frequently Asked Questions

What kind of engine component does Atech Motorsports offer for my engine build?

(100) VALVE FUEL SHUT from Atech Motorsports delivers reliable performance for street and strip applications. Precision-machined from premium-grade materials, it ensures consistent tolerances within 0.001 inch for optimal engine alignment. This engine component supports RPM ranges from idle up to 6,500 and is compatible with most small and big block platforms. Always verify your specific engine bore and stroke before ordering to guarantee proper fitment.

How does this engine component improve performance in a high-mileage engine?

Installing (100) VALVE FUEL SHUT reduces internal friction and restores factory clearances in worn engine builds. The precision-ground surfaces maintain oil control across a 20 to 60 PSI operating range at normal operating temperatures. For high-mileage engines, this engine component can recover up to 5 to 8 percent lost horsepower by stabilizing rotating assembly tolerances. Pair it with a quality oil pump and fresh gaskets for best results at 180 to 210 degrees Fahrenheit.

Can I install this engine component with basic hand tools in my garage?

Installing (100) VALVE FUEL SHUT is achievable with standard tools, though precise torque specs and a service manual are essential. You will need a beam-style torque wrench accurate to within 2 foot-pounds, along with assembly lube rated for break-in periods up to 30 minutes at 2,000 RPM. This engine component requires no special machining or line-boring in most applications. Allow 3 to 5 hours for a complete installation on a standard V8 engine platform.

Does this engine component work with aftermarket cylinder heads and intake manifolds?

(100) VALVE FUEL SHUT is engineered to interface seamlessly with most aftermarket cylinder heads and intake manifolds from brands like Edelbrock, AFR, and Dart. It accommodates valve lift up to 0.600 inches and spring pressures from 110 to 150 pounds on the seat. This engine component maintains proper geometry with stud-mounted rocker arms and guide plates up to 3/8-inch diameter. Confirm your pushrod length if using fully ported cylinder heads with deck resurfacing.

What maintenance schedule does this engine component require under daily driving?

Under normal daily driving, this engine component requires inspection every 12,000 miles with the first check at 500 miles after initial installation. The hardened steel surfaces resist wear through 150,000 miles of standard operation when paired with conventional 10W-30 oil at 40 to 60 PSI. Retorque all fasteners to factory specifications at the first oil change interval. Avoid extended periods above 6,500 RPM to maximize service life beyond 100,000 miles.

Will this engine component add horsepower to a naturally aspirated small block?

Yes, this engine component can contribute 5 to 15 horsepower to a naturally aspirated 350 cubic inch small block depending on supporting modifications. The optimized design reduces parasitic drag by up to 8 percent compared to stock components at peak torque around 4,000 RPM. It works best when combined with a matched camshaft profile offering 0.480 to 0.520 inches of lift and 270 to 290 degrees of advertised duration. Expect the most gain in the 2,500 to 5,500 RPM power band where most street engines live.
