Ensure a proper fuel vapor seal on your 1979-1998 Mustang with this direct replacement breather valve seal from All Classic Parts. Over time, the original rubber seal between the fuel tank and breather valve dries out, cracks, and allows fuel vapors to escape, which can produce fuel odors in and around the vehicle. Swapping in a fresh seal eliminates that leak path and returns the evaporative emissions system to correct function.
Built to original equipment specifications. This seal matches the dimensions, durometer, and profile of the factory part, so it seats correctly against both the tank and the breather valve without modifications. Fit is confirmed against OEM part number F6TZ-9B076-AA, giving you a direct cross-reference for verification before you order.
Addresses the most common failure point on aged Fox and SN95 fuel systems. The breather valve seal on these Mustangs sees constant exposure to fuel vapors, temperature cycling, and age-related hardening. A rotted seal cannot maintain a proper seam, and no amount of tightening compensates for a collapsed or cracked rubber component. Replacing the seal directly resolves the root cause rather than masking the symptom.
