Those are what I use to external mount a pump on a frame rail. If not? Well the frame rail becomes a speaker/amplifier from front to rear on boxed frames.

my walbro is just hose clamped to where the stock pump was.
it's weird actually, the fuller the tank is, the louder the thing gets.
either way, i was thinking it was going to die, then i heard a few other walbros in peoples cars and they were equally loud.
