No more leaks! Perfect!
by T J from Fort Gratiot, Michigan on October 23, 2012
The exact part needed to solve fuel connection leak for the old outboard pressure style gas tanks. Special o-ring that you can't just get anywhere. Iboats had them, and got them to me quickly with very reasonable shipping. Thanks Iboats!
