Yes, Directly after installing the new fuel filter on my 89 SHO, when I turned the key on for the first time the fuel pump was louder than normal.
I cycled the key about 10-12 times, to prime the fuel filter and lines.
When the pump sounded normal again, I started the engine. Started just like it should.
Just my experience, hope this helps.

...just turn up the stereo. That's what I do. 
Seriously, though - the lower backpressure may allow loose clearances in the pump to float around more. The Walbro units are very quiet compared to the stock Ford. When I put mine in, I couldn't tell if it was working or not until I started the car. It makes NO noise.
