The pump works however I have recently found that it will not stop your carb from loading up with fuel if the tank is higher. But if you lower the mounting position of the pump, it will stop. If you have the vibration pump this may be difficult but it works on the pulse unit. You can test this before you mount it by priming the pump with fuel and the fuel line disconnected from the engine and in-hand. If fuel starts siphoning out, obviously its too high. A Cline or Iron Bay regulator will stop the siphoning though and may be a better solution for you.
