I recently installed a fuel filter and I think i did it right.

I cut the fuel line between carb and fuel tank and installed with arrow pointing toward the carb.

I ran the quad after and no issues

 

Sounds like you did it right o me, are you having an issue with it?

 

if im thinking of the same filter you used its correct, the only reason for the arrow is that on the filter i used the filter paper inside it is in a sort of funnel shape, so you actually want it in the opposite position compared to using it as a funnel so that the flow of fuel doesnt tear a hole in the centre of it where the dirt would built up, instead it builds up around the bottom of it, closed to the casing where it is stronger. so basically im pretty sure you have it in correctly
