Greddy / Vortech Rattling Fuel Line
 

I've got a Greddy setup on my '92 and everything seems to be working well. At idle, I get this very annoying rattle that seems to be coming from the fuel pump. I'm running a Vortech FMU and a bipes, so the timing is stock at idle. At cruising RPM the rattle goes away. It seems to run fine the entire time.

Check the Vortech lines, they can work when reversed, but give you vibrations in the fuel lines.

That fixed it! Thanks
