Fuel line size

MsTurner79 · Mar 23, 2015

I have a 2002 mercury 9.9 4 stroke 323 cc. What is the fuel line size on the inside of the outboard? I can't find it in my manual.

Thanks
Matt

Take the old line out and measure the hose/fittings or take it with you when you go to buy the replacement.

Thats what I did.

I THINK it was 1/4" from my fuel pump to the carb, but I'm not sure. I know from the tank to the pump was 3/8".

Just pulled the line from pump to carb and got 3/16
