"One-way" fuel line valve..?

My pump :

Isn't it able to aspire gas from the tank? It's given for 3-5 psi and 30 gallons per hour.
And if the mechanical pump is just behind it, the combined suction of both pumps won't be enough to quickly fill the fuel line toward the carb?
In theory, that should work. I would mount the pump near the tank simply because that's the way it's designed to work.
