Hi All,<br /><br />I inherited a small Zodiac with no instructions or advice on how to use. It is the one with the high pressure floor that requires you pump it up to 11 PSI. <br /><br />I have the pump which also has a pressure gauge on it, and i am not sure if i am missing a piece to inflate the floor properly.<br /><br />To be specific. I can inflate the tubes for the sides and can inflate the floor a bit but there is not a tight enough seal to inflate to 11 PSI. And if i could inflate it that much all the air will rush out trying to put the cap on the opening. Am i missing a valve? Am i missing an adaptor? DO YOU USE THE SAME ADAPTOR TO FILL THE TUBES AS THE HIGH PRESSURE FLOOR?<br /><br />ANY HELP WOULD BE GREATLY APPRECIATED. I HAVE A DATE WITH THE LAKE ON SAT. <br /><br />Thanks
