Check valve seal replacement
A check valve seal keeps the valve sealed into the tank opening so fuel vapor and liquid cannot bypass it. When the seal hardens, cracks or loses its shape, vapors can escape and a fuel smell may develop near the tank. Fuel exposure is the main cause of wear, so seals in older tanks are often replaced during a fuel system service.
Before fitting a new seal, clean the tank flange and the valve body so no old material or debris remains. Seat the seal evenly and tighten the retaining parts gradually so the seal compresses without distortion. Check for leaks after the system is reassembled.
- Replace the seal whenever the valve is removed
- Inspect the tank flange for dents or corrosion
- Check the valve for free movement before reinstalling
