fuel regulator buzzing?

[garry goodall]

HI all,

I have just replaced a FSE regulator with a SARD one as it was buzzing when on light throttle however the SARD one has now started to make a buzzing sound but this time on idle and when blipping the throttle, anyone know what i'm doing wrong?

on my old GT this happened aswell with a SARD one also? these are the genuine ones BTW i dont do fakes lol

thanks for your help.

what fuel pressure are you running? what fuel pump do you have? is your tank full with petrol? what injectors are you running?

Could well be a feature of the SARD unit if you old did it, that never had any issues?

3.2 bar, standard fuel pump (i believe), standard injectors

yeah could be but its wierd, just went and fired the car up and the noise is gone ? so might do it when its warm, i think am gunna get a td fuel pump on it anyway

sure its not a loose bracket or nut on the regulator? vibrations can sound like buzzing

all bolts are nice and tight, the noise increases if i remove the vacuum, i think its the diaphram ? i have sent for a replacement now, only just had it setup on the rolling road aswell
