the thing you need to realize about the factory siphon in the tank, is that it is a venturi that is created from return fuel pressure. when you slosh the fuel to the left of the tank in a right turn, the fuel pump starves, there is no fuel at all coming through the regulator because the regulator is not allowing any bypass below its fuel pressure setting. therefore you have no return fuel to operate the venturi, and the factory over-tank siphon is dead, and will not function again until the system is up to full fuel pressure.
this is why when some of us make a hard and long enough right hand turn below a half tank, our cars are literally stranded on the side of the road until we add fuel to the tank. because no matter how long you sit there and wait, that siphon is not going to work without full fuel pressure. |
