Here's what I ended up with. I really had just forgotten that I bought this Airtex pump a while back, and also forgot that I had previously figured out how I was going to do the wiring till it just dawned on me while I was at work today. This is a V8 harness, which means, it has a factory harness end for an in-tank fuel pump. And when I pulled that pump to rebuild the tank system, I made sure to clip the harness from off the old fuel pump and I saved it in my box of stuff for this project. So instead of having to worry about wiring up a new circuit, I figure this one will probably work. (I hope....) At least, the pig-tail is long enough that it easily reaches over the top of the tank, and to where I have the pick up line running down the passenger side of the frame.
So all I needed to do was hard wire the clipped pig-tail from the old V8 pump to the new pump, then find a spot on the frame where the pump could go. Yesterday, I spent an hour poking and prodding up front for a good power feed, then I figured out a place to install the pump, and was ready to do the job.... but today I spent an hour just doing the job with the existing wiring already in place. Take a good look, since by the time it rains on Friday, this will all be just as dirty as the rest of the underside of the truck.

Primed the line with a turn of the key, checked for leaks, and then test drove for kicks. I'm pretty sure the IP is also a bit quieter now. It's one reason I had originally wanted to put the electric in. Although it never sounded bad, I had always wondered if the IP wasn't just a bit louder than it should be because it was essentially doing the pick-up work. Time will tell, but it might have (fingers crossed) helped with the pinging knock I have always had. Since I don't always hear it, and since it is sometimes quieter than other times, I can't be sure till I put another few hundred miles on it. However, the last time I allowed myself to think about it, I was starting to go down the line of thinking that noise might be fuel flow related.
