At LONG last. Our first run of production fuel rails. Supply should now be secure for as long as I'm in business 
First, the pix:
It'll be another week or so before I can provide photos of a rail installed on an engine.
Assembly includes
Aluminum fuel rail, clear anodized so it is safe to use with any percentage of ethanol-based fuel.
QTY 2 mounting brackets (stainless steel) with fasteners
QTY 2 black anodized fittings (-8AN Flare to AN Straight Cut Thread 3/4-16 with O-Rings)
QTY 1 black anodized plug for the fuel pressure port (1/8-27 NPT)
Pricing: $235 + shipping
These will be going up on the site next week or so. In the meantime, PM me for purchase requests. If you don't like the black fittings, you can provide your own or PM me for other options.

Hey Dan, be careful using stainless steel brackets on an aluminum head. Galvanic corrosion will F you in no time flat if there is no insulating layer between the two.....those two metals do not like each other.
Super nice bracket though, hats off to you !

Anodizing to the rescue!

Maybe talking about where they bolt to the intake?

The big concern there would be the fasteners, so if you're using the oem studs and nuts to which the brackets mount, there shouldn't be any issue. If you're worried about where the hole in the bracket and the bracket surfaces touch the intact, a light coating of copper anti-seize should prevent galvanic corrosion.

I was. You already mentioned the rail was anodized. I would be more inclined to use a rubber grommet or nylon washed. Mi dos centavos..

Yeah, I was sorta thinking I'd do similar - actually, my manifold is painted anyway, but thin nylon washers could be enough... or yeah, antisieze...
(rather deal with that than aluminum brackets fatiguing!)

We went over galvanic corrosion in an engineering class and there is a chart that shows what is called "Galvanic Series." Basically, the farther apart the two metals are in the galvanic series, the more susceptible they are to corrosion when they are next to each other--the result of an anode and cathode reacting.
There is a common misconception when using metals that are thought to not corrode as bad interacting with each other. Take the two metals mentioned, for example, aluminum and stainless steel. While both of these have good corrosion resistance on their own, they have a large galvanic difference. When coupled, the aluminum acts as an anode, and the stainless steel as a cathode and the aluminum corrodes away.
more info can be found here for those interested:
