So lately it seems after I drive my car for a little over 20 minutes i start hearing my Fuel pump Make a RC Whine. Every time I accelerate I hear the Whine...even at idle it's Whinning.


Does that mean my Fuel pump is on it's way out or what?...it's getting annoying as hell.

 

how long have you had it & how much hp/tq you running?

 

its my understanding that the walbro whines like that all the time. not having one, i can't tell you from experience, but i've heard it more than a few times.

 

if its predominantly louder than what it was prior, then start savin your pennies for a new one.

my external walbro 255 began making that same whine. these things are cheap, but not exactly the most reliable.

 

It's normal specially during summer time when it's hot out.

 

it's normal all the time...it is what it is, if you don't want the whine try another fuel pump(but they will do the same too I imagine) try the bosch if it really bothers you

 

So nothing to worry about? Mine is doing the same thing.

 

yeah my walbro 255 whines like crazy too. Not as bad as some evo owners ive heard with walbro 255 but it definitely will whine

 

yeah mine whines too but im use to it.

 

the guy is saying his pump is making irregular noises than what it's usually doing, and you guys are saying its normal?

dehhhhh....

 

Walbros are known to have a common whine. Even if it did just start happening like in this situation, its very likely natural.

 

normal! when it's hot out, it make a lot of noise.

 

i've had a total of 4 internal 255's, and 1 external 255 on various setups. random LOUD high pitched whines arent exactly normal. especially if it is periodic. this is with weather up to 115* where i live, as well as the many locals i interact with on a daily basis.


to the OP...a 255 is $100, i'd say buy a new one for a solid piece of mind. Isn't worth possibly risking a motor over a probable defunct pump.

just my 2cents.

 

This might sound weird but I like the whine, LOL.

 

not at all, i love the whine too hahah
