A - Procedure for fuel tank more than 3/4 full
- Remove filler cap from fuel tank filler neck.
- Disconnect 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, the hose should only be inserted to the 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 the marking on drain hose (arrow) coincides with rim of the filler neck.
- If the hose does not go in easily, lubricate lightly with engine oil. Never use lubricants containing silicone.
B - Procedure for fuel tank less than 3/4 full
