I was told that a walboro 255 was put in my car, and it definately sounds different than my 95 z28 did with the stock pump. Any of you guys have videos of your walboro's priming so i can compare the sound? Thanks guys

 

No sound clips, or video.. but it has a hummmm to it. Nothing to be concerned about. More fuel being delivered, a little bit more noise!

 

previous owner just confirmed it was a walbro 255. thanks for the help man
