AIR LINE IN OLD SHOCK WON'T COME OUT, CAP REMOVED BUT STUCK INSIDE, WHAT NEXT?

Hello, the only thing you can do here is try to apply penetrant to the seized fitting of the airline. Let it sit. Maybe apply a small amount of heat. Seek professional guidance if nothing else to see if he can be salvaged with professional tools. Going slow and being patient is the most important step you can take - it might be all the difference. If it fractures, you'll have to replace the air line also. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
