Fuel line?

what size of fuel line does the carb'd accords use? I'm in canada so it'll be in

1/4 inch
or
5/16 inch

I looked on majestic honda it says 7.5 I'm assuming mm? is this correct? what is that in canadian values?

I'm thinking that maybe there is no exact match here in canada, regardless I'm replacing the fuel hose that goes from the fuel pump in the tank to the filter by the tank and then a peice of hose will connect it to the steal pipe running the length of the car. I got 1/4 inch hose but its a b!tch to get on, and I'm looking at the factory line and it 1/4 looks a little small......

any ideas?
