I am trying to change the fuel filter in my 1991 740 SW (non-Turbo)

I am following chilton manul.

a. Disabled fuel filter fuse.
b. Located the fuel filter

However I am not able to get the fuel filter removed from the piping. The bolt seems to be dead tight and wd20 does not seem to work.

I am assuming someone has better step by step instructions on how to do this with pictures.

Can you please post a picture or the manual on how to do this step-by-step?

 

If you look you will see that fuel filter has hex on both sides under banjo fitting. They are different sizes on each end. Some gorilla tightened mine so tight I thought I would never get it off. With two wrenches you will be able to. I don't bother with the fuse thing, not that much fuel comes out anyway.....
