The fuel connector to my double hose tank (for my 57 big twin) is beginning to leak. I noticed the o ring on the tank side connector is pretty dried up and cracked, hence the leaking. I cant find a replacement o ring anywhere, does anyone know the dimensions of the o ring so I could source a generic online?>
That O ring is easily available at an OMC dealer. $2 each here. Change both. Use dentist picks to do it. search this forum for the part number as it has been discussed before.
301824 from any Evinrude dealer. It is not a stock size, so you won't find it in the hardware store. Sierra aftermarket 18-7111 is a poor substitute, as it is an attempt at replacing it with a stock o-ring.
