Install a inline filter

[xida]

Hi to all.
On my 2003 Liberty KJ there are two lines coming off the fuel pump on top of the gas tank
going into the fuel filter but only one line coming out of the filter to the gas line going to the motor.
Does anyone know why two lines. I thought of putting a clear inline filter instead of the one that's on it.
Can one of the two lines on top be plugged so only one could be used ??
Thanks.

I 'think' thats also the regulator. So that would be a return hose.
