Title: fuel pump hissing!?
Post by: joesgti on April 28, 2010, 11:43:31 am
just noticed last night that my fuel pump hisses after i turn the engine off, i have the autotech fuel pump. ive read on another forum that its normal due to the friction boiling the gas?!  :confused: and is normal.

anybody shed any light??  :smiley:

oh and the car is running absolutly fine, pulling harder than ever!  :smiley:

Might just be the pressure dropping back to ambient after the car has stopped as its a pressurised system when running?

Check for a snake under your bonnet...   :laugh:

Oh, and no, mine doesn't hiss.
I wonder if your HPFP ring seal could be starting to leak as your upgrade re-uses the old pump ring.

They just got a correct sized O ring from the local motor factors, but you maybe lucky and the VW dealer will have the official one in stock.

Anyone this is Joe we are talking about, I am sure he will have some old rizla papers that would do the job just fine  :laugh: :laugh:
