As mentioned on other replies

This is what I use on a daily basis

Fit new diesel filter

Remove pipe connected to filter housing that goes to the fuel pump on the engine

Use the pump to suck diesel through until about 1/8 - 1/4 ltr has passed through

Reconnect fuel pump pipe

Then start engine

It really is that simple

NOTE - I always replace oil and filter first and restart engine then check oil level etc etc BEFORE beginning to replace fuel filter as this prevents the dreaded cam chain jumping due to a "deflated" chain tensioner
