Scratch that -
Just searched 2005 5.3 fuel rail on eBay and found several ranging from $90 to $250. It would be nice to be able to run those aluminum setups with the threaded ends and receive the fuel on the rear passenger side, making plumbing clean and easy.

These are cheap enough to buy and try with your manifold, the angry pig has a stock manifold and aluminum fuel rails that look similar to these.

Yes! Found a couple similar to that, but that’s definitely the cheapest I’ve seen.
Want to run -6AN fittings from the pump to the intake and everything in between instead of the push/quick connect fittings.
So another puzzle piece is the actual line. Thought about trying to run a hardline for a portion of that distance, but there’s the issue of having to convert from inverted flare on the hardline to the JIC on the flex lines. Not sure if there’s anything to gain running a hardline over just a length of stainless flex from rear to front.(?)

I ran stainless hard line on mine, everything is 37° flare (JIC) so the fittings to back and forth between hard and soft lines are standard fittings.
Lot of pictures in my build thread of the bulkhead brackets and fittings I used.

You bet...Thanks man
Can we get back to posting photos in your build thread, it's getting kind of wordy lately.
Damn, You're good! 
I did a lot of manifold research but zero fuel rail research. The best manifold for your money seems to be the Trailblazer SS from the mid 2000s. You can get a new OEM from Rockauto for $130 or so. The other low pro OEM style are a lot and actually dont do as well. If you go aftermarket, the pretty aluminum ones are actually crap for power. The FAST manifold seems to be the best. I watch videos on utoob from Richard Holdener. He does really in-depth tests of a lot of things like cams and heads. His tests are the reason I am bone stock and if I changed anything it would be the TB SS manifold.
Megadoomer,
Let me ask a question, you're talking about the intake manifold, correct and a low profile one. So, if I went with the low pro one I could raise the whole motor and gain more clearance for the oil pan, right.

Tech talk without pictures is just talk, we need more pictures if you want to keep our interest.
Fuel pumps, if you make a plate for the top of your tank and hang a Bosch 044 pump off a simple mount you will have a solid system for about the same money as the OEM things you are looking at.
This is what I made for my pig tank that has an LS engine.

Completely understand where you’re coming from. Many indications show that the OEM LS is pretty dialed in. The change of fuel rails isn’t about power, it’s about my preference for absolutely zero quick-connects in this setup.
I like your thinking here, Scrappy. This could possibly kill a couple birds (ducks) with a single stone.
You can go higher but remember where your transmission and xfer are going.

Not only pictures but we need video too.
Intake manifolds are going to make very little difference (especially seat of the pants dyno) on a stock engine, I would go with a low pro stock manifold, engine placement options will outweigh and fractional HP gains between high or low manifold. Look at the RMP that the difference comes into play here.
Ya, every cam and intake sacrifice low end torque. I live around the 4k mark and would never see the gain and only see the loss.
I think very few of these FJ55’s will ever see a drag strip and most will live at or under 2500 RPM in normal use. I love the fractional HP gains game as much as the next guy but in reality when we are talking about a stock LS engine in a pig a good tune is way more important than any single bolt on part.
