Gurgling Sound

Had someone stop over with a 98 that has a gurgling sound under the dash when she accelerates. It seems to be coming from the heater core any thoughts das2123.:smile:

From under the dash...I am not sure. Under the hood, I would say faulty "radiator" cap.

Well it seems that the fuel pump is making noises one being a gurgling sound. Than it is transmitting up the fuel line and reverberating to the firewall by the overflow bottle.

Well thats a first for me (why I love these forums, constant information).

Are you gonna replace the fuel pump?

Not sure it is running and I advised the customer, there decision. It also has only 36K on it I did do the valve cover as 2 spark plug wells had oil in them.
