That must be a weird one for Basscat, because I have never seen any other model that you could not access all your pumps. I have owned 4 different models (85 Phelix, 85 Caracal, 91 P2, 01 P3 ) and have been able to access every pump without removing anything. That is why I did not answer this question early this morning when I first saw it, I thought someone may have changed the tank setup.
