that right i just put a walbro 255 pump in an 05' evo and it runs fine havent driven it yet but when i turn the ignition on and your sapposed to here the legondary walbro wine.....i get nothing, it quieter than the stock one. is this a problem, mabye weak, i didnt do a pressure test but when you unplug it the car does stall. any suggestions

 

I have had mine in for 6 months now with no noise too. I was expecting the worst from what everyone was telling me. I was pleasently suprised.

 

It changes all the time. You'll probably hear it later. Mine was silent at first, but now it can be heard at full whine most of the time.

 

thanks guys it had me worried of a min. now i can put the seat back in.

 

You'll hear it in time. The first year I had my Walbro pump it was pretty quiet. After the second year I started to notice it whine. It's not that bad, you just get used to it.

 

I heard nothing for 2-3 days, now its like a have a mini super charger in the trunk.

 

GO jump on it for a minute then come to a stop and listen!!

Mine is kinda moody! if im light on the peddle I wont hear a thing!!

HTH

 

Install an Aeromotive A-1000! That is death there!

 

key word supposed not every part will be as loud as they are cut out to be , a good majority might but not all

 

Maybe because when you turn the key on the pump does not prime on the evo. I only runs under crank and while running.

 

I have one on my Dodge Daytona Shelby Z and it is quiter than the stock fuel pump was.

 

Haha, mine has mood swings as well. Sometimes i hear it, other times its asleep

 

same here ,when i put it in my 03 V111 it was silent for a couple of months and then i started to hear it all the time after that,no big deal as long as it works correctly

 

What exactly causes the noise? Vibration to where it mounts inside the fuel tank? I've never done a fuel pump so i'm not sure how they bolt up in the tank. If its like i'm guessing, is there any way to insulate it as to reduce noise?

 

You will eventually hear it. When I put mine in it was not noticeble, now it starting to buzz a little.
