Due to a series of events yesterday I had to travel 76 miles after
the fuel light came on in my 14 year old Audi A4 1.9 tdi estate. I
was pulling a trailer with about 150kg in it. Can anyone beat that?

Years ago, (many years because it was when my father was alive and he
died in 1960, so 1950's) cars would have a 'reserve tank'. IIRC there
was actually no such tank, but the normal take-off from the tank was a
little way off the bottom, with a second take-off lower down and
nearer to the bottom, so in effect the lowest part of the tank was the
reserve. Again IIRC there was a tap somewhere in the fuel pipe that
you opened manually to allow the engine to use the 'reserve tank'.
Quite how you knew when to open that tap I don't know; presumably when
the car chugged to a halt!


My Herald 13/60 had a fuel pipe that was inserted at an angle, the
normal orientation meant that the bottom part of the pipe was
horizontal in the tank. Turning the fitting where the pipe entered
rotated the pipe 90 deg, so that the bottom part of the pipe in the
tank was now at the deepest part. Worked a treat.
