norrs Donating Members 448 Member For: 17y 6m 4d Gender: Male Location: Darwin Posted 03/07/14 11:57 PM Share Posted 03/07/14 11:57 PM Ok its been a while since I posted as I sold the old car. Anyway, I now have an FG F6 and I'm back.It has a Process West Surge tank (old style single pump) mounted under the passenger side. I swear that the whining is louder than it was a month ago. The whining is louder than the radio. I tried to record it today for you guys to listen too. I just need to know if this is normal or is it about to sh*t it's self.I ran the car the other day and jumped underneath it. The mounting seems secure, I'm certain it is coming from the pump.Hopefully the MP3 of the recording will be linked below for you guys to listen to. This was taken in the car park idling. and then at the end I turn the car off. As you can hear it the frequency of the whine changes while idling.Fuel Pump.mp3 Link to comment Share on other sites More sharing options...

However, the noise is the same regardless of whether I have just started it in the morning or if I have driven for an hour.My fuel was 75% but remember I'm talking about the pump on my surge tank not the one in the original tank.This was recorded in the drivers seat with the windows wound up. You can't hear yourself think outside of the car. I have to yell at the girl at drive throughs. I might do another recording out of the car.Is there a way to test if it is on the way out, is it fluctuating or dropping furl pressure? Is this one of the things I can log on my obd Scanner app?The changing in the pitch of the whining while at idle is my main concern, surely that isn't normal.

Nice rubber mounts to body and rubber around the pump. Anyway, I'll take it into you mechanic to test the pressure. Link to comment Share on other sites More sharing options...

I never got to the bottom of why (it will do it on a brand new pump) but one theory that I suspect is that maybe the screw on thing on the front of a new pump that we all throw in the bin may help keep it quiet but I never tried using it with it on. Keeping fuel cool helps but that surge tank setup definately heats the fuel up heaps and makes the problem heaps worse. It sounds like you have not run this set up on a hot summers day as it will go 10x troppo. Link to comment Share on other sites More sharing options...
