How are yous supposed to remove the fuel pressure in the CIS system? I'm trying to remove the fuel distributor and I disconnected a line at the canister thing in front of the metering plate (EHA valve I think?). I disconnected this line because it is the only one where I can fit a canister underneath. It just leaks and leaks, I removed about 1 liter of fuel and it doesn't show any sign of stopping...

I did the same thing during spring, I remember doing something to relieve pressure in the system, but I don't remember how I did it. Spillage was minimal.

I looked behind the battery for the fuel pump relay, but the relays aren't setup like the pictures I'm finding.

I'm already pissed off at the thing and I just started working on it

Provided that the fuel pump is not running, remove the filler cap of the tank.(Tank pressurization is normal.)
Then open the line between the FD and the pressure regulator.
