How to release pressure in the fuel system

[Waylander264]

Hi all.  I'm new to the forum, so Hi! first of all.

Not sure this is the right forum to ask the question, but I am after advice on how to release the pressure in the fuel system before I remove the intake manifold.

I recently replaced the fuel injectors but didn't need to worry about the pressure as one of them was leaking anyway.  Now i need to get the manifold off again but obviously the fuel pump is engaged, so I need to depressurise first.

Any advice gratefully received.
