for some reason, when the car is running, i noticed that i cannot hear the loud whine of my walbro fuel pump anymore... but my car still runs... is it messed up?
actually.. damn.. i just noticed that when i turn the key to the 'on' position, i can't hear the whine either... i'm assuming the FP is still working since i can drive the car... but its not pressurizing or something so not making the whine?

Just a thought but... if you just filled up with gas your pump will be much quieter... Sound waves can't travel as easily through liquids as they do through air.
The only time I can hear my walbro pump is when I'm well below 1/4 tank. --------------------  Project ST204.5 99.88946% complete... |

The only time I can hear my walbro pump is when I'm well below 1/4 tank. hm... i did notice that it was a lot quieter the day after i filled it up.. maybe i was a bit paranoid since the car wasn't driving too good. luckily re-uploading the tune fixed it. QUOTE (Dr_Tweak @ Sep 17, 2008 - 9:43 AM) I've observed that often the Walbro pumps are quiet at first, until they get warmed up. I have also heard them randomly stop whining randomly for various periods of time. -Doc that's good. hah at least now i know it's still working properly This post has been edited by elvasoshexai: Sep 18, 2008 - 12:01 AM -------------------- |
