2023 Toyota Gr86 Fuel System Problems

Your fuel line on the driver side of the engine bay is rubbing against the underside of the hood when it closes, creating visible wear marks on the line. If this rubbing continues, it could eventually damage the fuel line and cause a fuel leak, which could lead to a fire. Other GR86 and BRZ owners have reported the same issue, and there have been multiple reported engine bay fires on these models. The fix will likely involve repositioning or protecting the fuel line so it no longer contacts the hood.

If the wear continues, it could eventually damage the fuel lines and create a leak.

The fuel lines on the right side of your engine bay are rubbing against nearby components and wearing away. The outer rubber coating of the fuel lines is being damaged enough that material is being removed from the surface. This wear could eventually lead to fuel leaks if not addressed. The fix would likely involve repositioning or protecting the fuel lines, or adjusting whatever component is causing the contact.
