I have an 83 Euro model 280SE with I6 engine, alloy fuel distributor.

I have disconnected all the lines and removed the four top screws. It won't come off.

Can someone direct me to where I can find out how to remove this unit?

Thanks.

Does the M110 have the same big rubber boot as the later CIS cars? If so you need to loosen/remove the hose clamps on the boot that connects the throttle body underneath the fuel distributor unit.

If two of the screws that were removed are socket head (torx) screws, replace them.
The FD is held to the air meter by three slot headed screws; the third is in line with, and perhaps hidden by, the connection to the control pressure regulator.
