My gs-r is 100% stock, except for a walbro 255lph fuel pump that I installed about 2 month ago. I havn't had any noise problems till about a week ago. The noise is very loud.

I was fixing my antenna and had to remove my back seat. When I did, I can hear the noise extermely loud where the pump is. However, when i lean down to the exhaust, i hear the noise too. Also, under the hood, the noise is near the ABS box. However, it's loudest at the fuel pump.

Now, i have heard that those pumps are usually louder than the stock ones, but if that's true, I don't understand why the noise came after like 2 month...

Could that have messed up my CAT since it would be running a bit richer?

TIA

 

but u didnt notice the noise till u removed your back seat. is it more like a whining noise?

 

No , i heard the noise before i took the seats off. I just happened to be fixing the antenna so i took the seats out.

 

yes walbro's are naturally loud. i noticed mine right when it was put in.

 

Yea, it's loud, you can hear the whine from outside the car. I like it, I know when it's done priming before I start my car everyday.

 

this sucks man...it's loud as ****..gets annoying.

 

you'll forget about it sooner or later

 

HAHA you got a good old walbro .. you should hear my pump.. DAMN thing is loud and after a half a tank you can hear it over open downpipe..lol but they are good pumps

 

mine loud as funk , youll get used to it

 

You guys ever seen that black GN TT with the turbo's that stick out through the hoods?
There is a video of it somewhere, listen to that fuel pump, and then tell me yours is loud

 

is the black gn tt smoking when its on the dyno? that one?

 

nothing is louder than the fuel pumps that GM used on all of their trucks for the last 15 years.

good Lord, i work at a harbor and when a Chevy is coming with a boat you can almost hear their fuel pumps before you hear their flowmasters...

i've got this video on my CPU; it is bad ***.
if i knew how to post it i would.

 

The Walbro actually isn't that bad. Be glad you don't have to live with an inline pump mounted on your firewall.

This is true...my friend's GM is so effing loud.

If you think a Walbro is loud, try riding in a Honda with an Aermotive pump.

 

Thanks for the info.. I guess i'll just have to turn up the cd player a bit more, hehe

 

and they get louder if your low on fuel. so keep gas in the tank

 

^^^ thanks I've been looking for this

 

Yea, I have it on my comp too, I love that car.
P. S. I was just too lazy to post the link...
I have another video of it, an in-car view, that one you can hear the pumps.

 

why do you have a 255lph on a stock car?

Doing some of the minor work first so when it's time to boost, it doesn't take forever.

 

holy mother of coincidence. i finally heard mine whine...and i did exactly what u did. i checked the rear right tire fender...where it was loudest. then i went near the exhaust..and i heard it there. but then i went to the engine bay..and i faintly heard it there too. i'm so glad you posted...now i know its just my fuel pump. what a relief. thanks.

however...mine doesnt' whine all the time...and yesterday is actually the first time i heard it. and i installed my turbo about 4000 miles ago. weird.

 

fuel pumps are actually the loudest when you are running low on gas.

 

No better way to start your day, when you get inside your car, shut the door and put the key in the ignition... Turn the key slightly hear *wahhhhhhhhhhhhhhhhhhh....hhhhhhhhhhhmmmm...* It's like a big sigh of relief after releasing a monster ****, best thing you've felt/heard in a long time. Then you start the car.. Okay, I'm done.. lol

 

Mine is loud as ****...espescially with the back seats out. I actually like the sound though .
