Fuel Shut Off Valve #12 w/o Return

The Fuel Shut Off Valve #12 w/o Return from MPD Racing is a precision-engineered safety component designed for vehicles requiring manual fuel system isolation. Whether you're building a high-performance race car, restoring a classic, or modifying a street machine, this valve serves as a critical failsafe to cut fuel supply instantly in emergency situations or during maintenance. Without a return line configuration, this design is ideal for fuel systems where excess fuel is not recirculated to the tank, making it a popular choice among drag racers, off-road enthusiasts, and engine builders working with carbureted or direct-feed fuel systems.

This valve operates through a simple yet effective mechanism—a manual shutoff lever interrupts fuel flow at the source, preventing fuel from reaching the carburetor or injectors when closed. The #12 designation refers to the specific port size and flow rating, designed to handle fuel volumes typical of small-block to mid-sized engine applications. Constructed with durability in mind, MPD Racing's design eliminates unnecessary return plumbing, reducing complexity in the fuel system while maintaining reliability under high-pressure conditions. The compact footprint (4.7 x 3.05 x 6.15 inches) and lightweight construction (0.84 lbs) make installation straightforward in tight engine bays without adding significant weight.

Mechanics and fabricators favor this valve for carbureted performance builds, fuel cell systems, and any application where fuel flow control matters during tuning or emergency shutdown. Installation requires splicing the valve into the fuel line between the tank and carburetor—a task within reach of experienced DIYers or professional shops. Verify your fuel line diameter and pressure rating before ordering; the #12 size accommodates standard fuel line specifications common to V8 engines and smaller-displacement high-revving platforms. This is genuine MPD Racing equipment backed by years of racing program validation.
