So I just received my new fuel screen that goes in the tank with the new brass washers
One small and a big one so my question is the small fix perfect on the big tube where the screen goes if I try the one that supposed to go on it it’s very loose and it’s the same way on the smaller fuel line the small brass washer is loose on the smaller line that screw into the tank ?

Also which way do I install the brass washers to seat against the fuel tank threads or behind the fuel tube so the jam nut tighten them ?
