With gas tank upside down lube the plastic filter with wd-40 and use the needle nose to gently pull it out. If you are patient and careful you might get it out with minimal damage. I always use a new petcock with o ring you can get it from honda direct parts.. google it. Petcock kit will cost about $25, make sure you clean the the tank before you install the new petcock. Use the "The Works" toilet cleaner look in the faq section for details. Peace !!
