A - Procedure for more than 3/4 full fuel tank
^ Remove filler cap from fuel tank filler neck.





^ Detach tapered adapter -2- from shaft end -1- of VAS 5190.
^ Make a mark (arrow) on hose at distance a = 1465 mm from end of drain hose using insulating tape.





^ Fit shaft end -1- of fuel extractor VAS 5190 onto fuel tank filler neck.
^ Push drain hose into fuel tank until marking on drain hose (arrow) coincides with shaft end.





Note: On the lower end of the fuel filler unit, there is a spherical valve -2- in the fuel tank -1-, which must not be excessively pressured or damaged via the siphoning hose -3-. Therefore, hose should only be inserted to marking (arrow).

^ Remove fuel from tank as much as possible via fuel filler unit.
^ Carefully remove siphoning hose.
^ Remove fuel pump.
^ Siphon remaining fuel through opening for fuel pump.

Note:
^ The procedure when using a fuel extractor without shaft end is basically the same.





^ In this case make a mark on drain hose at distance a = 980 mm from end of drain hose using insulating tape. The drain hose is fitted properly when marking on drain hose (arrow) coincides with rim of filler neck.
^ If the hose does not go in easily, lubricate lightly with engine oil. Never use lubricants containing silicone.

B - Procedure for less than 3/4 full fuel tank
^ Remove fuel pump.
^ Siphon fuel through opening for fuel pump.
