Normal fuel line design does not have the ability to switch tanks. An individually designed system does not benefit from the experience of thousands of Kitfoxes out there. Some have tried to eliminate "one tank low" but there is little evidence of anyone actually experiencing fuel starvation with the standard arrangement. There have been reports of starvation when tanks are individually controlled.

Can't imagine "bad gas". Water, yes. Sediment, unlikely. Since it happened when he switched tanks he could still be feeding off the "good" full tank, though I would hope he's seeing flow in both tanks as he flies, or maybe is switching back and forth between tanks.
The pulse line is not your typical plastic tube. Most 1/4" fuel line has a wall about 3/32" thick. Pulse line has about an 1/8" plus wall thickness. The thin line dampens the pulses, weakening the fuel pump action.

Now a glider pilot, too.
