1969 Chevelle Malibu Sport Coupe - EFI350, THM350. 3/8" Feed line, 5/16" return line, and 1/4" vapor recovery line from LH tank run across the crossmember at the to the RH rail. There is the one remaining 1/4" out let from the switch and there is a vent line on the frame right in front of this port. Do I really need two cannisters or can I just tee the vent lines together into one cannister? It's difficult to know just how much you don't know until you know it. The 1/4" vapor line goes into a tee under the switching valve and passes off to a hardline in the RH rail. One set of 3/8" and 5/16" lines go down the RH rail to the engine. Family is not an important thing. If you can t tell yourself the truth, who can you tell it to? Anyone know where I can find a diagram of the vent and fuel lines for a dual tank setup on a '79 K-10?
