Fuel filter change Discovery 1 300 TDI

How to change your fuel filter

Quite a short blog this one, but one I keep seeing on forums "how tdo I change my fuel filter".  This is how its done.

Firstly remove the top screw on the filter holder, see below.  Unscrew the old filter and dispose of the fuel in the filter, or poor it into the new filter, whatever you feel is appropriate.

Remove the fuel filter holder top screw.

Fill the new filter to the top with diesel (whats in the old one is never enough so you will need to top it up).  Screw the filter back on the filter holder by hand (do not over tighten) and put the screw back in the fuel filter holder and tighten with a 10mm spanner, do not over tighten it, it will snap.

Then start your Landy and let it run for 1-2 mins just to ensure you have no air trapped in the fuel system.  If it does not run well, or stalls, its likely you have air in the fuel system, take the filter off, fill it again and prime the system using the lever on the back of the lift pump and start it again.

Simples.
