So I am just buttoning up a few things and wondering if the below picture of the fuel lines is correct? It doesn't seem right at all but I can't really read the pictures in the manual well enough to tell. It's a 1969 Buick skylark hardtop coupe. 350. Non ac.
You should have 2 lines that go to the fuel pump in front and 1 that vents to the atmosphere (tank vent) the cars from 1970 and earlier earlier do not have a vented gas cap. HTH. :TU:
