Put a walbro 255 in my car the other day. I did the it the access panel way. Since there was nothing there, I expected to be able to hear the pump some. Now, I've got it all sealed up and put back together, but the whine is still quite audible. What gives?

 

Mine sounds like that too, and it doesn't matter if the pump is hot or cold. Not real loud but you can deffinatly hear it in the car and alittle bit when outside the car. I've had it out twice and everything seems perfecly fine and fuel pressure is holding a steady 60psi. It's pretty much been like this for 4 months and I can't really figure out why.

 

Hmm, that sucks. I do have some old dynamat lying around. Didn't really want it to come to that, but I can't think of anything else.

 

My pump does the same thing, I even sent the first one back.....2nd one sounds the same

 

Just put duals with dumps on there and the only tim you will hear it is when you turn the key on. . Mine is a little louder than the stocker but I cannot hear it over my exhaust.

Same whine......

 

So it seems like many of us have this problem...

Somebody has to have a fix for it?

 

I dont think it is a problem, especially seeing that we all have it.

 

I think it's a problem cause it gives me a headache sometimes. Ok, so it's not a "problem," but it is quite annoying.

And I don't like naggy passengers complaining about another thing.

 

I have it too. Are you guys always refilling the tank before it gets to 1/4 of a tank ?

 

It sould not be that loud! Mine is not really louder than stock, it just makes a different noise. Like I said before I can only hear mine when I first turn the key on because my exhaust is so loud. I went out to the car just now for a listen and it is still nice and quiet. I also have all of the sound deadening insulation under the carpet out of the car.

My does the same thing. I just open up my Borla. Can't hear it anymore.

 

Guys ... make sure your filter socks are clean of debris and that your fuel filter is changed. The whining should quiet down significantly. Mine did.

 

I swapped in the pump with a brand new sock and put in a brand new filter at the same time.

 

mine is also loud as hell..its annoying..i just open the qtec

 

Mine was loud for a few days when it had a harder time pumping as my sock was dirty and my gas tank had debris. But once again ... the noise should decrease if you're able to reduce the stress on it.

Or maybe I;m getting used to it
