I need some help. I have a non vented tank with a vented cap. When I open cap it is under high pressure..
This is a new tank from opgi. I had to replace it cause the original tank had a hole at the top, and when I filled up, gas fumes filled the car.
Side by side the tanks look the same. No vent tubes.
Previously, the fuel pump had to be changed. The fuel pump had only one line, but there were two lines coming from the tank. Based on other post the second line is a return line. I got a new pump with both lines. now everything is connected back up.
