I'm not going to lie the Walbro makes some noise when it gets hot. It will be quiter than if you run out of fuel though. It's hard to tell but that looks like a booster pump. If it is make sure the fuse to it is good. If one of the two isn't working that could explain your lack of fuel. The thing about using booster pumps is that if either pump goes out you have just enough gas to go boom.
