I have a 2000 Tahoe 5.3l the other week . The truck started running rough at idle. I checked the vac. hose to the fuel regulator gas came out. Went to advanced auto got a new one cleaned out the old one ,only held in by a clip. started the truck now the new fuel regulator is making noise pull off the vac. hose noise stopped. Question is this normal it's quite loud can hear this over engine and fan noise. Did I do something wrong with install seemed straight forward or did I get a bad fuel regulator.
