My Bilge pump isn't drawing properly, and I can hear air hissing at various points in the line. My line appears be in several parts rather than one continuous line. The portion of the line runing from under the engine mount, under the floor to the bilge is tightly fused in and I can't get any sort of leverage to pull it out. I am thinking of running a thinner gauge hose through the existing hose into the bilge and the coupling the ends with original gauge hose but am concerened with the effect on the performance of the bilge.

Has anyone else had this problem ?
