This 1987 Chevy El Camino, with an LS6 motor, is in so we can repair and replace the fuel lines.
This car has a ground strap off the engine that goes to the fire wall. It came loose and the engine, electronics and everything else tried to ground through the braided stainless steel lines. The fuel lines became corroded where they were grounding, and the corrosion poked holes in the inner part of the fuel lines.
That resulted in fuel leaking and spraying all over the firewall. We ended up repairing the correct ground, and we added an additional ground beneath the motor.
We’re also replacing the braided stainless fuel lines with some that are covered with fabric and can’t act as a ground in the future.
