Yeah im replacing the pump and filter and plunger seal and wiring for pump toyota said they have seen this happen before but not this bad one of the mechanics said loose connection but this is the original pump never touched. Also as this connection is right at the very top of the tank so unless the tank is on full 100% all the time to the motor over heating i dont think the fuel level would affect the prime power connection to the pump if so it should short the fuse when it overheating.
