Have you tried e-mail? You might want to try connecting through Viair on Facebook
I answer all emails, and return all calls.
If you need repair parts, send me an email at LanceM@viaircorp.com - its my screen name and my email address. You can speed things up by taking a photo of the compressor with the head assembly off so I can see the direction of the reed valve. I will send you a detailed list of parts/prices and a credit card authorization to pay for the parts. We usually ship within 48 hours.
