-- Slide the suction hose into the fuel tank far enough so the mark applied earlier -arrow- is aligned with the shaft piece.

-- Empty the fuel tank through the fuel filler tube.

-- Remove the extracting hose carefully.

NOTE:

Proceed the same way if the fuel siphoning device available does not have a shaft piece.

In this case, apply a mark -arrow- using insulating tape on hose at length -a- = 1235 mm from end of suction hose -1-. The suction hose is inserted correctly when the marking applied earlier aligns with the lip of the fuel filler neck.
