I'm removing the fuel tank from a '78 240 wagon, and have everything disconnected and unbolted except for the metal junction on the filler neck. I can see the tube above and to the rear of the right wheelwell, but can't see how it comes apart. The Haynes manual shows a pair of screwclamps connecting the fill tube with the tank neck, but naturally this illustration doesn't resemble the metal accordion-looking connection on this car. Anyone done this? Thanks!

It's easiest to seperate the filler tube inside the trunk. There is a rubber hose that conects the upper and lower halves. Just undo the clamps and remove the hose. Also there should be a vent hose running from the tank to the upper half of the fill neck. Disconect the hose, and the tank with lower filler tube still attached comes out from the bottom.
