Fuel Filter Change '84 300D

[Kbike]

Hello All:
It's been about 2 years and 10K miles since the fuel filters have been changed on my sons '84 300D. This will be the first time I've done it myself. I figured I do it this weekend before the weather turns too cold. Any things to look out for when doing this? Any trickes? I'm planning on changing both the in-line & spin on filter. After the new filters are in place - do I just use the manual thumb pump to remove any air in the system?
Thanks in advance,
Kbike
