GRABOTE Fuel Shut-Off Solenoid Kit — Briggs & Stratton 846639 Replacement, Direct-Install with Wire Harnesses

This compact, ready-to-install solenoid restores proper fuel shutoff on mowers and small engines without needing a factory part. Machined to the same basic dimensions as the original, it includes a washer and wire harnesses so you can swap it in quickly. The unit’s dimensions — approximately 1.72 inches tall with a 1.02-inch base diameter — make it a straightforward aftermarket substitute for a wide list of model numbers from multiple brands.

How does this solenoid stop fuel when I turn off the engine?

The solenoid interrupts fuel flow by moving a plunger that closes the line when power is removed, preventing fuel from reaching the carburetor or pump. It’s an electrically operated valve designed to be open while the engine runs and closed at shutdown, which prevents post-shutdown fuel seepage and flooding.

• Electromagnet actuates a plunger to block fuel flow.
• Operates when ignition circuit is switched on/off.
• Includes wiring harnesses for straightforward electrical connection.

How do I install the solenoid safely and quickly?

Installation is simple with basic hand tools: isolate the fuel line, remove the old solenoid, and fasten the replacement using a wrench. Make sure the fuel line is clamped or capped before disconnecting to avoid spills, and reconnect the wiring so the solenoid receives power with the ignition on.

• Clamp or cap the fuel line to prevent fuel loss during swap.
