Anyone know why my Revvo tank would be leaking? It was working fine. I took it off my mod to put another tank on the mod. When I came back to the Revvo it had leaked all over my desk. I checked my coil and the center fill port. It all seemed screwed together correctly. This is my second coil by the way. I don't think my first coil did this. I am about ready to give up on the Revvo, wasting too much juice!
