Review on Check Valve Return Non Return Petrol by Jeff Callier

The check valves in my garden tractor's fuel pump have failed so it will not work. I installed one of those check valves between the fuel pump and carburetor and saved over $100 without having to replace the fuel pump. Also, fuel does not flow back into the fuel tank when the tractor is stationary between mowing. This significantly reduces engine cranking time during a cold start. These check valves are great. You can also use it to bleed your car's brakes without having a second person open and close the bleed holes on the calipers. Great value for money and delivery was quick. I am very happy with this purchase.
