Kymco People 150 fuel filter

[dwarnimont]

My fuel filter has the inlet from gas tank and has TWO output lines.  One goes just prior to Carb and the other goes to gas/air flow on the other side of carb, bypassing carb.  I don't understand whets going on.  The reason i ask is that i don't believe i will find this odd fuel filter and want to understand to enable me using a non OEM option that may not have two lines coming out of the bottom of fuel filter

@dwarnimont, pls assure you really mean your fuelfilter (pls see pic)
..upper pic is fuelfilter
..lower pic is fuelpump
And yes, there are fuelfilters with two outlets, but very rarely used in motorcycles.
Maybe you take a pic of your scoots innerts.
Further questions welcome.
