Citroën C4 1.4 16V – Do I need to remove the intake manifold to replace an injector?

Hello,

I have a Citroën C4 1.4 16V petrol (KFU engine) and I’m trying to replace one of the fuel injectors.

My question is:

Do I need to remove the entire intake manifold to replace a single injector, or is it possible to remove the fuel rail and injector without removing the manifold?

I want to avoid unnecessary disassembly.

Thanks in advance!

Thank you for the video, I really appreciate the help.

However, I believe that engine in the video is slightly different from mine. I have a Citroën C4 1.4 16V (KFU / ET3J4 engine), and the fuel rail seems to be mounted directly to the intake manifold with very limited space near the firewall.

Can anyone confirm whether, on this specific engine, the fuel rail can be removed without removing or loosening the intake manifold? Or does the manifold have to come off to replace an injector?

Thanks in advance
