Review on 🔧 Farmunion Fuel Non Return Valve: Efficient One-Way Check Valve for Petrol and Diesel – Aluminum Alloy Construction by Jerry Frey

Installed on a '67 Chevelle SS fuel line. I had an issue with draining the fuel back into the tank after about three days of inactivity. I have a mechanical fuel pump and it took me about 10 seconds to pump fuel into my Edelbrock 750 before starting. After installing this check valve 8 inches from the carburetor inlet, the engine will start within seconds. Ease of installation. Make sure the arrow is pointing in the same direction as the fuel flow. Hose clamps are not included. Appears to be a quality item.
