I was replacing all the fuel lines on my dads pontoon boat and managed to break one of the nipples off of the cup looking cover that the fuel screen goes in. I cannot find one anywhere that will work,I did find a aluminum one off a old 40 horse merc motor but cannot get it to seal,I tried the old gasket and the one from the 40 horse motor and both blow fuel when I pump the fuel bulb. I think the 40 horse housing may be smaller than the stock plastic housing off the 70 horse motor,I cannot find a new one anywhere,my google foo powers have let me down. Does anyone know where I could get a new or used one?
