[Saloon-lovers] MkIX fuel lines

Could somebody who has a Right Hand Drive 1960 (approx) Mark 9,
please tell me EXACTLY what is the correct routing for the fuel
overflow tubes,
For Example:

  1. Inboard or Outboard of the Steering Column ?
  2. Out through the cut-out in the Wheel arch or down through the
    side
    etc, etc.

Dave,
Our 1960 RHD MkIX - I went to check the lines so I could report back…
horror! - the lines feed out from the tops of the fuel inlet bodies,
down inside of the steering column and go… nowwhere - just open ended

  • any excess fuel will pour out onto the ground - something is not quite
    right!!!
    Our Aussie manual for SU carbs just shows the lines - no indication of
    where they go.
    I guess they should go back to the tank directly?

No, they don’t return. Excess fuel goes to the ground. You can decide just
where :slight_smile:
S-Type fuel overflow lines just stop in the middle of nowhere.
Originally, they were longer, and got clipped on beside the oil filter mounting,
so fuel would spill down the side of the engine block. You can see the clip in
the parts book. A friend with rebuilt carbs by Burlen, got short pipes which
stop at the bottom of the fuel chamber. I have the original pipes, but they are
a very unusual shape :slight_smile:
Similarly, there is always fuel open to the atmosphere in your auxiliary
starting carb in the reservoir. That is why you can get wonderful explosions if
these engines spit back :-), and a wonderful smell of fuel on hot days in the
sunshine :slight_smile:
