    Would it be possible for you to post a picture of your L79 fuel line showing the same location that I'm referencing?
    Send me your e-mail address to my PM and I'll send you some pic's.

        Jim,

        Thank you for the great picture. In my mind, that is what I was thinking the "ideal" orientation of the fuel line to manifold should be. But, I'm being led to believe that I'm basically making a mountain out of a mole hill and that the line workers that installed these lines 48 years ago probably didn't have a micrometer out measuring each and every fuel line. If I ever have the opportunity (fuel filter change) to remove the line from the carburetor, I'll fiddle with it. Again, thanks for the picture (great looking engine BTW)

          Leif,

          Comparing your photos to Leif's, it looks like your fuel line needs to move 2-3mm forward to avoid interference with the manifold runner. Your replacement line was bent by the manufacturer to within a reasonably close shape. It's not unusual that it needs a little final forming by you.

          These steel lines are quite workable so you should be able to nudge it forward a bit by hand to take care of this.

              Leif, Just like Mark say's above, it's not difficult to tweak the bends to get a nice fit keeping a air space in the tighter area's. I don't have a picture going across the engine but here is a pic of the vertical line on my 300hp engine that I had the same issues.

                  My 300hp is about the same - the original line very nearly touches the intake manifold and the thermostat housing; clearly wasn't a design consideration.

                    John,
                    Always great to have your knowledgeable input. I have to agree that it must not have been a design priority as it doesn't seem to affect the drivability of the car. Very nice engine compartment, as well. Thanks again.
