I have Mk5 Golf 2.0 TDI and it has a fuel leak at the fuel cooler where the pipes attach to the bracket. The blue pipe that returns to the tank has a push release and came off no problem. However the brown pipe doesn't appear to have the same release, although the connection looks similar.

Is this standard and if so how do I release the other pipe? I don't want to force it and end up breaking it.
