5.   Prime the fuel system using the manual pump of the coarse fuel 

filter. 

6.   Start the engine, check the junction for leaks. If necessary, 

additionally tighten the replaceable filters. 

7.   In case of leakage, unscrew the replaceable fuel filter; check the 

condition of the sealing ring and its bearing seat. 

 

ATTENTION!
