Same area, the fuel filter. Ones on top and the other is on the bottom. So I figured why not

The engine only has 1 filter right? That wix site shows a primary and secondary filter. Which one is the one that threads on under the injection pump? Just remove it and fill the new one with diesel and install right? No bleeding the lines?

Yep, 1. There's no fuel filter under the injection pump. It's under the rear portion of the intake plenum

And I just wing on the new one with a little diesel or some motor oil in it right? Just something to prime the motor? Then I pump the handle a couple times and I'm good to go?

Yeah, if it starts. Prime it with the lift pump manual handle until fuel comes out the bleeder screw above it on the side of the manifold.

Then close the bleeder screw.

I just recently had the same problem with mine. You have to put that screw in part first. Take it off of the filter and screw it up in there, there should be a slot on it for a big flat head screwdriver. Or you could be like me and use a gasket scraper. Once you get it tight screw the filter on. Its a retarded setup but thats what the deal was with mine. You just have to get that screw on part tight before you put the filter on. I know that was a half a** explanation but you should get the idea.....

If you go and take the fuel heater off isn't the stud going to be too long for the filter to screw back on?

This whole thread is jacked!
If your WIF sensor is leaking because of stripped threads, then I would do away with the WIF sensor, and use the filter suggested up there^^^^^ somewhere.

If your fuel heater(above your filter) is leaking, then I would try replacing the o-ring that goes between the heater and the head.

Yes, it will be too long.
