What solution does Technician A suggest for a permanently kinked sample hose?

Replacing a permanently kinked sample hose is the best course of action as it ensures the integrity and functionality of the emissions testing equipment. A kinked hose can disrupt airflow and lead to inaccurate readings during the smog check process. Therefore, cutting out the damaged section could temporarily alleviate the issue, but it doesn't provide a long-term, reliable solution. Ultimately, replacing the entire hose guarantees that the equipment operates effectively and delivers precise results, maintaining the standards required in emissions testing.

The replacement provides a fresh and undamaged section of hose free from any restrictions or damage, which could result in better flow rates and more accurate sampling. Simply removing and cleaning the filters may not address the underlying issue of the hose's integrity, while cutting out only a section might not restore optimal performance. Additionally, adding more filters doesn't solve the problem of a compromised hose.
