I would try some KY to lubricate the threads so you can get the fitting tighter. I don't know exactly what type of fitting you have but a hose coupling like the one in this link will allow you to screw to pieces of 1.5" corigated hose together. Again more KY.

Evidently, on inspected vessels the coast gaurd wants the suction strainer to be 3x the area of the suction hose so this doesn't meet that requirement but then again it is pretty unlikely that you have an inspected vessel. http://www.beckson.com/images/STV-1-1_2at600.jpg http://www.beckson.com/hose.html Josh Muckley S/V Sea Hawk 1989 C&C 37+ Solomons, MD On Apr 27, 2015 8:59 AM, "Eric Frank via CnC-List" <cnc-list@cnc-list.com> wrote: > The 1.5 inch ID corrugated hose that runs from the bilge to a manual pump > in the cockpit seems to be leaking in air just where the corrugated hose > connects to an adaptor that screws into the hose with the threads of the > corrugation and then provides a male 1.5 inch end that fits inside the > strainer.
