When The Tank Is More Than 3/4 Full
Secure the fuel extracting device VAS 5190 ground strap to a bare area on the chassis.
-- Remove the cone piece -2- from the shaft piece -1- of the fuel extracting device VAS 5190.
-- Using insulating tape, apply a mark -arrow- on the suction hose at length of 1180 mm -a- from the end.
-- Remove the cap from the fuel filler tube.
-- Insert the shaft piece -1- from the fuel extracting device VAS 5190 into the fuel tank filler tube.
-- Slide suction hose into the fuel tank until the mark applied earlier -arrow- aligns with the shaft piece.
A ball valve -2- that must not be damaged by the suction hose -3- is located in the fuel tank -1- at the lower end of the filler tube. Therefore, slide in the suction hose only up to the mark -arrow- applied earlier.
-- Drain the fuel tank as much as possible via the fuel filler tube.
-- Carefully pull out the suction hose.
When no more fuel can be extracted, the tank is emptied only enough for the sensor flange to be opened without danger. The tank may be removed while containing the remaining fuel.
If work must be performed on the fuel pump or on the sensor, refer to WHEN THE TANK IS LESS THAN 3/4 FULL .
