Really easy to change in a Nemo 1.4HdI!!! Less than 10 minute job.
So this was a replacement fuel filter for a Citroen Nemo 1.HdI. Could not have been easier. One star screw and one crosshead screw to remove. The fuel pipes disconnected with finger pressure alone. Hinged it forward, disconnected the electrical connection. Popped the other one in and pumped the fuel up using the bulb on the other side of the engine. Done in less than 10 minutes.
Now, considering the nightmare that some fuel filter replacements can be - this really couldn't be any easier.
