I know I have a leak in two places but I am trying to figure out why the area around the fuel filter is coated with oil.

The first leak is in the transmission oil pan near the back by the transfer case. I am going to change the gasket here and see if this fixes it.

The second leak is a small one somewhere on the transfer case. I am assuming it is in one of the seals that I can't change by myself. I am going to just watch this one for now and keep the transfer case filled.

I mention the two leaks above in case one thinks these could be the root of my issue which is oil is coating my fuel filter and the surrounding hoses/tubes. It doesn't smell of anything - no gas smell or sweet transmission fluid. Any idea of where the oil can come from?
 
Does the fuel filter sort of line up with the u-joint area coming out of the transfer case? If so, it may be the rear output seal leaking, and the oil is being thrown over to the fuel filter area from the driveshaft spinning.
 
Is the master cylinder full? There is a brake line that runs through there... and they do rot out.

It sort of is aligned, but, I don't see evidence of thrown fluid between the rear output seal and the fuel filter - say above onto the insulation or elsewhere.
