Only steel, copper and plastic lines of plasticised, light and temperature-
stabilized PA 11 or PA 12 (e.g. Mecanyl RWTL) pursuant to DIN 73378
may be used for the fuel lines.
Since the lines normally cannot be routed with a constant rising gradient,
the internal diameter must not be allowed to exceed a certain size. Air
or gas bubbles will accumulate in lines with an internal diameter of more
than 4 mm and these will cause malfunctions whilst the heater is
operating if the lines sag or are routed downwards. The diameters
specified in Figure 9 will ensure that bubbles do not form.
The lines should not be routed downwards from the metering pump to
the heater.
Unsupported fuel lines must be secured to prevent them sagging. They
must be installed in such a way that they cannot be damaged by flying

road chippings and high temperatures (exhaust line).
The fuel lines must be secure at the connections using hose clips to
prevent their slipping.
