You have two soft rubber ends (3 inches or so) of vacuum line with a hard plastic line in between. The line runs down to the fuel filter fuel pressure regulator. Buy some vacuum lines and slice the soft line where it ends (don't worry about slicing THROUGH the hard plastic line) and simply install new soft rubber line at both ends. I need to do a write up on this. It's that time again -- THE MANGO LIGHT IS LIT UP IN THE SKY!!!!!!!!!!!!!
