Toyota 2c 2.0L Diesel, Fuel filter replacement?

Hi. I wonder could anyone give me a brief overview of fuel filter replacement on toyota 2c motor, constructed 1989. I have it 4 years and have not done it yet. I think i can figure out the assembly, disassembly steps but not sure about priming etc.

Thank you in advance.

If someone has similar motor i would be happy to trade all my mechanical experience. Which with a toyota is very little, thankfully.
