I went and bought some stock metal fuel lines from an 88 mustang and replaced the nylon svo ones on my car. I also put just a stock fuel pump in it. Supposedly there is supposed to be a ground wire? I talked to a guy and he had cut one of the wires that goes through the floor of the trunk and simply screwed it to the floor next to where the spare tire goes. He said he thought it was a brown or yellow wire. He couldn't remember. Its all svo wiring if that makes a difference? Should I have this ground and which wire is it if I do need it?
