I took off my tank to check the airfilter and didn't notice the two rubber dampers had fell out of place. I was only able to find one of them. I tried to replace it but I guess you must have to have both for them to fit. I plan on putting them back with some adhisive, but I only have one. Any recommendations on what to use? I thought about using the rubber foam sheet from the arts and crafts section at wal-mart and just cut to size. Anyone have an extra laying around? The vibs are bad around 5K and hope to fix it soon!
