I bought a few year old tank off of a member here. I think it's 3 gallon. Two 1 1/4 inlets and 1 3/4 outlet at the the top rear of the tank pointing backwards. There is a baffle where the tank transitions to the outlet, but it still wants to dump at the hit if there is Anything in the tank. I had a filter on the outlet, but then that just gets saturated and plugged up. I'm going to start cutting and rewelding today unless somebody can tell me what I'm doing wrong??
