Just wanted to let you all know this thread helped me set up the used Marineland C-360 that I got last week. I used a small screwdriver to get the primer button back up, then decided not to risk pushing it down again so I disconnected the hose block, opened the flow control lever, and started the siphon the old fashion way (with my mouth). Fair warning if you try it this way, be quick to shut the flow control lever as soon as you get the water siphoning. My shirt got a little wet before I got it closed. Then I just reconnected the block and let the canister fill. Jlennon, how did you apply the oil? I think that I'm going to try using a light machine oil. Thanks again to all for this thread.
