Ever since the summer triple digits hit, i hear a loud whining noise coming from the back from where the walbro is located. It only whines when the AC is on and when the cars been running for a while. Some dude told me that the noise is a sign of a bad fuel pump, but then my other buddy said that the noise is a standard walbro. So is it time for me to get a new fuel pump? if my buddy who told me it is standard is reading this, im not second guessing you..haha. well i kinda am.

 

Walbro pumps whine like women my friend....

 

It get's pretty loud as the weather warms up.

 

ok whew! thanks fellas

 

mine has had the noise since it got put in

 

yup. it pump whines as the gas gets hotter, i came to that conclusion.

 

Some are worse than others

 

Walbros whine. Normal.

 

it does after a long trip.

 

normal

 

huh...it freaked me out bc i drove it for half a year then all of a sudden i hear the whine....but i guess its cuz the triple digit temps. but thanks

 

LoL, you've never heard the nickname "winebro?

 

I never knew they got louder as the temperature went up. I always heard mine whine but just recently it has gotten louder and of course the temperatures have gotten hotter.

 

it also whines when your gas level is low

 

With my back seats in mines pretty quiet unless it's around 1/4 tank of gas. When the back seats are out all I hear is that thing whining. Nothing to worry about though.
