Still having fuel problem?

gas is still dripping out of the fuel line vent under the car?? i installed a fuel pump from inside the hatch and ever since then fuel has been leaking out of the vent of one of the lines under the tank.... i have never drove the car yet or started it so how the heck is this happening? it is coming out of the vent holes not running down the hose from top..

Disconnect the fuel filter and let it drain into a container. Either put 12 volts on the fuel pump prime connector or turn KOEO for 2 seconds and let the fuel pump pull fuel out of the tank. Afterwards see if the vent is still dripping. Once you have a sufficient air gap at the vent hose inside the tank, it should stop dripping.

Connect the system back up and try priming again with KOEO. See what happens. Hopefully the dripping will stop.

You didn't hook up the hoses wrong when you did the pump swap did you? The end of the vent hose should be well above the upper level of the fuel tank.

Let us know what happens
