Q: Why is gas leaking around my 6150-21-6750 exhaust cover?
A: This usually occurs due to thermal warping or bolt fatigue in high-hour PC400 machines. Replacing the cover with our reinforced 6150-21-6750 ensures a perfect seal and prevents turbocharger inefficiency.
Q: My fuel tank vacuum valve is stuck. Can I just replace the cap 07050-41200?
A: Yes. The 07050-41200 fuel cap is designed with a specific venting mechanism. A faulty cap leads to engine stalling. Installing a new Genuine Replacement cap resolves tank pressure issues immediately.
