I am about finished installing a return style fuel system on my 03 Cobra. The system consists of Fore triple hat with twin Walbro GSX342s, Fore regulator and rails, -10 supply line and -8 return. I am triple checking everything for leaks and verifying my wiring. When checking my wiring I noticed when I run the pumps separately one pump is louder than the other. Has anyone else noticed this? I've heard these pumps are louder than the stock pumps but not one louder than the other. Could it be that one pump is isolated beter in the hat than the other?
