I would check all your connections for sure. Are you running it externally?

 I put my feed pump in a calm area in the sump and I even put it inside a 200 micron filter sock to guarantee bubbles weren't getting in. I ruled that possibility out already as well. 
All the fitting connections look good and all have silicone around them as well or extra protection. The only thing I can think of is the uniseal which I will try to replace today or tomorrow.
