Hello and Welcome to justanswer...
The fuel filter on your vehicle unscrews off....and the new one screws on -reversal of removal..
Often they can be very tight but you can try it by hand... or if its too tight - use an oil filter wrench ( supplied at car accessory / tool shops quite cheaply ) to grip it to unscrew it.
Fit the new one - but before you do - fill it with diesel - that helps the bleed process to go quickly - and dont fit it with the removal tool - just screw it up tight - but hand tight only.
I Sincerely XXXXX XXXXX have helped you - Please ask me if you need more help...
Kind Rgds, MIKE
