Eliminating the safety roll-over valve on the vent did not solve the fuel leaking issue. I discovered that the electrical connector I have on the Aeromotive pump is becoming saturated with fuel when the tank is full. I recently rerouted the electrical wires away from the fuel lines so I could tell if the fuel was getting on the wires from the fuel lines. The connector is still becoming saturated with fuel. I'm thinking fuel is wicking up the pump wires from the pump. I sent a message to Boyd Tanks to find out if they've seen this before. Here's a video that shows fuel dripping off of the connector.
