Fuel Line Mod Done - Still Having Hot Restart Issues

Could it be the way you have the filter mounted? I have a the clear filter too but it is much closer to the carb and is horizontal instead of vertical like yours.

It looks like it's draining back down and the filter needs to refill and get pressure again so the engine can suck the fuel. Since there's a bubble coming up, it seems like air is filling the filter and the is engine getting pockets of air then fuel. My filter looks like it is almost full when the car is just sitting.
