Marineland C360 leaking! Please help

[Nero1]

I have a marineland C360 for about 3 years now without any issues. This week it started a very slow dripping leak under one of the clamps. I inspected the filter completly and found no cracks. This made me think that is was the oring so today I purchased and insatalled a new o-ring. To my surprise the leak got much worse If you can provide me with any ideas to fix this please let me know.

Im only familiar with the 400 but try dismantling the whole thing and run pieces under a faucet to pinpoint a leak spot

any luck fixing the leak? mine is leaking where the hose set clamps to the top of the canister, its coming from the output side...plus it wont prime...i force water thru the inlet side and it wont go into the filter, its like its clogged but its not...i can take the top off and place it on the water surface and it pumps...put it back on the canister which is full of water and it squirts once and thats it.
