Walbro Pump 4x4 install.
Thought I would post this up for those interested. Just mocked up with no wiring yet but everything fits.
Couple pics of hoses and fitting needed.
Where pump is mounted. Had to put it here because there is no room for it in the frame rail of a SCSB 4x4. Used self tapping Stainless screws. Metal was soft and very easy to drill in this spot.
Pump mounted, no hoses yet.
No braided hoses on in this pic, end is capped to prevent gas from draining on your face.
180 degree fitting from behind the pump, inlet side.
Pump outlet side.
180 degree fitting out of filter going back to pump inlet, and pressure side from pump return.

Even though it was a cramped area compared to your truck I didn't have to use any more braided hose or fittings.

Figured I should finish what I started.
Using a Nelson wiring harness first and second pics, the small end is the fuse block, the large end is the relay. Sorry you can't see the wire color after I put the wire covers on.

Pic of the braided lines all connected and tightened prior to mounting.
Make damm sure all your connections are TIGHT before mounting them, there is pretty much no room to get any wrenches in the spaces where all the fitting are. The only one I left just snugged was the 180 degree fitting coming out of the filter going to the pump's inlet.
There are a lot of fuel lines and wiring in the space where this fitting resides and you may need to tweak it's postion slightly to give clearance.
Don't forget the filter's mounting bracket!

A pic of the pump and relay mounted close to the pump. Make sure you have a GOOD ground here. The red is positive to the pump and black is ground. You cannot see the green wire from the relay here but it goes back up to the fuel pump relay Grey wire shown in the previos post.
Sorry for the blurry pics, hard to get a good shot from one foot away laying on the ground.
Hope this post help anyone who needed it.
