[quote=Dogboy][quote=dartsailors]How about those of us that don't have drain plugs? All I've got is an access port at the back of each hull. Do I take a sheet of rubber, tape it over the access port and then make a small hole for the tubing?[/quote]
I would purchase an extra access port cover, drill a hole in the top of it and tap it for a 1/8” or 1/4” NPT pipe fitting. Then purchase a brass pipe fitting with an Male NPT thread on one end and a barbed hose connection on the opposite end. Thread the pipe fitting into the access port cover, push a 10” long hose onto the other end, and then install the access port into the hull to allow you to pressurize the hull.
