A fuel delivery system for a fuel cell ( 400 ) includes a substrate ( 404 ) having a cavity ( 402 ) formed therein, an o-ring ( 408 ) embedded within the cavity, and a detachable tube ( 410 ) inserted though and retained within the o-ring. The tube ( 408 ), when inserted through the o-ring ( 408 ), forces the o-ring to expand and fill the cavity ( 402 ) thereby forming a liquid tight seal for the transfer of liquid ( 414 ) to a fuel cell chamber ( 416 ).
