Technical data

Air Top 2000 ST Fuel supply

7.5.2. Installation and attachment

The metering pump must be secured with a vibration-damping mounting

(for example a rubberised clip). Its installation position is limited as shown

in Figures 14 and 15 in order to ensure effective automatic bleeding.

As a result of the risk of corrosion, only genuine Webasto parts may be

used for the plug connections between the metering pump and the meter-

ing pump wiring harness.

7.6. Fuel filter

Only a Webasto filter, order no. 487 171, is allowed to be used if the fuel

is expected to be contaminated. Install vertically if possible, however at

least horizontally (check flow direction).
