Sunsun canister filter 304b leaking

[Scott1242]

Hey everyone I have the sunsun 304b it worked well till it started leaking. The gasket around the top seems to be shot. Works, If I put it on really slow and push hard to seal. If the power jolts from the storms we have had it leaks again. I'm not looking to spend more than 150...please help me find a canister filter that does not leak. 90gallon swim tank.
