GOOFIT Vacuum Fuel Switch (Three-Hose Type), Two-Piece Set, Compatible with Off-Road Vehicles/Motorcycles/ATVs, Vacuum Diaphragm Fuel Valve, Specifically for Carburetors--BIEMMEDUE

Key Product Benefits

Automatic Vacuum Control: This product is a vacuum diaphragm fuel supply switch. It automatically opens the fuel supply when the engine starts and creates a vacuum in the intake manifold. When the engine stops, it closes automatically. This prevents fuel leaks at the carburetor and increases safety and convenience without manual intervention.

Standard Three-Wire Interface: Clean design with three connection wires:

Fuel Inlet Filter (from the tank)

Fuel Inlet Filter (to the carburetor)

Vacuum Filter (thin hose, connected to the intake manifold or carburetor base, provides the signal to open the switch)

Double Set: One set contains two identical vacuum switches – one for immediate replacement of the faulty part and one as a spare.

Ideal for fleet maintenance, workshops, or households with multiple vehicles – economical and efficient. It addresses common problems: issues with the original switch are directly replaced, such as fuel leaks after the engine is switched off, starting difficulties in cold weather, unstable fuel supply, or fuel entering the cylinder due to aging, cracking, or failure of the diaphragm seal.
