Lost my fuel cap overboard (yes I know I should have repaired the tether BEFORE it went under...)<br /><br />Have been to about a dozen marine stores this past week, but no one locally has one that will thread into the deck plate... What they do have are either too large, or too small...<br /><br />The internal dimensions of the threads (when measured with an "inside" caliper) is just a shade over 1.5"...<br /><br />The Perko 1 1/2 inch caps are too large to thread into the opening, and the 1 1/4 inch caps "fall" into the threaded hole in the deck plate...<br /><br />Any suggestions on where I might find one of these beasts without buying the whole deck plate assembly?<br /><br />Thanx in advance for any help...
