Ok, so 3 weeks ago I decided I wanted to build an air tank, Captain Slug's looked awesome, but it looked expensive (sp?) too! So I made a simpler one 3 days ago for about $21. After I used it for the past 2 days, the tubing just poped off the Hose Barb! So I cut the out-stretched pact off and put it back on, and today it did it again! Is there anyway to fix this? Heres a picture of the tank and barb.
