Through some research/advice I found my external pump must be mounted as low as possible to stay full of gas when powered off. I had to change my idea of using that little shelf for the pump.
Metal below is 1/8".



This plate doesn't make contact with the frame rail or the 45-degree crossmember so I used some pieces of 1/4" angle as supports. Without these a hard hit on a rock will leave the pump taking the weight of the truck. Not sure if I'll add a piece from the crossmember to the gas tank skid support piece or not.

Below is after I added some studs. I wanted to make changing out the pump and filter something I wouldn't have to pull the cab to do. Now I should be able to just reach under with a little socket wrench and undo the hardware without looking at it. Space will be tight.


I'm curious about opinions when welding something flat to something beveled like this weld here. I used the wire to fill the gap between the two pieces. The flat piece is right up against the tube, but the tube has a rounded edge. Does this make a strong weld?


Another example of filling a gap with wire. Not sure if this is adviseable or not.



First pass underneath upsidedown. getting better. Power down to "3" and wire speed at 28.




Second pass upsidedown, here's where I think I had it dialed in better. Power=2 WS=25. I found holding the gas nozzle in my left hand like a pen worked well.



My fuel rail has connections on the driver's side but tank is on passenger's. I tried running lines to driver's side but the crossmember area got confusing. This is what I settled on. 1" aluminum angle and self drilling/tapping screws.




Clerarance between lines and exhaust. Maybe I will wrap them.

Here's where those studs I welded in come into play. I cut down the hardware so I think I should be able to reach under when the cab is on to change the filter. I used one of the stock fuel line disconnencts on the rear filter connection.

I wanted to use 3/8" send fuel line but the pump outlet is 5/16" I found a conveninent fix for that. The filter is Purolator F64728 and has a 5/16" inlet and 3/8" outlet. Strange huh? It is for early Ford thunderbirds. The cardboard is temporary until I find some foam padding.
