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.
Oh right that is the filter, sorry. Well, I go with my previous statement. Hook a gauge up to the schrader valve and see if it falls under 40psi at WOT.
The walbro is an in-tank unit and it is pretty noisy when the tank gets low on fuel. The fuel cools it and keeps it quiet when it is submerged.

I've got the walbro 255 on return style...I really didn't notice much noise difference. Although I haven't driven it since like Feb...I miss it!!! If you had some of the foam wrap that comes around a lot of them, and depending on the insulation between the tank and inside...I can't imagine it would be too loud
