Fuel gauge gone funny

[Welshy_Pete]

I've noticed my fuel gauge has gone funny on my 306 hdi. I've done about 80miles with the light on now. Also one min it goes up then back down. I wanted to have a look also test the float to see if the dial changes etc.

I've checked the wiring going in to the fuel sender it looks fine.

I know how to take of the connector. But how do you take the 2 fuel pipes of?

Also do you need to run then pul the fuse out to clear the system before removing?

thanks
