Thanks for the help. Cactuspixie I do not have any power heads to prime the intake, on a tank that size I probably should.
I also tried Vaseline on the o-ring, apparently the Marienland 360 has this issue every time you clean the media, Marienland also sent me a couple extra o-rings because of the leaking.
I did go to my local pet store and picked up a new filter, I find you can get it cheaper else where I hope I made a good choice it is suppose to filter up to 265 gallons.
