What size is the Fuel hose that feeds the filter?

[Partzman23]

I need to know what size the fuel hose is that feeds the fuel filter. I know there are two different sizes of hoses, what are they? A friend said his Spyder is leaking fuel. I am going tomorrow to check it out.
It's for an '18 RTL.
TIA

As part of my replace everything when I purchased my 77K mile Spyder, I replaced the fuel filter which I recommend your friend does too. There were no leaks but the cords were showing through the pressure-side hoses: tank-to-filter and filter-to-Y-fitting. The pressure and return hoses are two different sizes -- I replaced both. Make sure you use the fuel hose clamps not worm gear clamps to ensure even tightening tension around the hoses. And search is your friend.
