Removal of air from fuel system (the petrol engine of 1.8 l)

The fuel system of the engine with a turbo-supercharging has no returnable fuel pipeline. For this reason after work with fuel pipelines or the fuel filter it is necessary to remove air from fuel system to exclude damages of the catalytic converter. It is possible to start the engine only after removal of air.

 PERFORMANCE ORDER

1. Include a starter, thus air will leave fuel system itself. This procedure can last some seconds.

Through 10 with interrupt procedure for a short time.

2. After start let's the engine work about 2 min. on single turns.
