7.3.1. Installation position
Before installing the metering pump, ensure that the maximum pressure
occurring at the pickup point is less than 0.2 bar.
It is advisable to install the metering pump in a cool place. The
permissible ambient temperature must not exceed + 20 °C at
any time during operation.
Metering pump and fuel lines must not be installed within range of
radiated heat from hot vehicle parts. A heat shield must be used if
applicable. The pump should preferably be installed near the tank.
7.3.2. Installation and attachment
The metering pump must be secured with a vibration-damping suspension.
Its installation position is limited as shown in Figs. 12 and 13 in order to
ensure effective auto-bleeding.

The sticker "Switch off heater before refuelling" must be affixed at a
suitable point.
