Why does the j30 only have 1 fuel filter?

[J30boy31]

I noticed there is only one fuel filter on the j30 but i see 2 lines running wouldnt it be better to add another fuel filter on the line next to it to?

The fuel return line wants a filter? I doubt that. The EVAP line does have a filter, elsewhere. What'you talkin' 'bout Willis?

The factory filter is rather generous in size and does it all, not to mention (as mentioned above)the other line is just return of unused, already filtered fuel back to the tank
