8.3. Fuel supply . The values for the permissible pressure at the fuel delivery point are

listed in the following table.

NOTE

A fuel feed line can normally be identified from the installed fuel filter.

Fuel may only

be taken from the return line with the special Webasto fuel

pickup (see Fig. 8).

The fuel pickup must be fitted so that any air or gas bubbles are

automatically discharged in the direction of the tank (see Fig. 8).

Air or gas bubbles may arise in the fuel line of the vehicle if there are

leaks in the carburetor or vehicle fuel pump or if the ambient

temperature is higher than the evaporation temperature of the fuel.

The fuel pickup should not be located near the engine, as gas bubbles

may form in the lines on account of heat radiated from the engine. This

may cause problems during combustion.
