For gravity-fed motorcycle fuel systems, need to fit a filter designed for such purpose.

I take the line off the filter and gas will flow even through the filter, I put back together and sometimes fuel still won't flow? The only thing I can think of to try is going to a bigger fuel line....
take the line off the filter and gas will flow even through the filter -- :S uncertain about what is being described? Could this scenario be re-stated differently -- perhaps in a clearer manner?
Am thinking that size of the fuel line is NOT an issue in this instance.
An obstructed fuel cap vent can cause fuel starvation, but usually happens while riding.
As known, when the engine isn't running, a vacuum-operated petcock is supposed to allow fuel flow only when set in the PRI position.
A kinked fuel line may cause fuel starvation.
Line should be fitted with smooth curves.
Length of the fuel line (below level inside the tank) doesn't matter.

Being "worse at a half a tank or less" casts suspicion toward an obstructed vent in the cap of the fuel tank.

If not already done, could also test ride with the petcock in PRI position, to see if it makes any difference in the symptoms.
