Hard Line fuel setup - check this jazz out - Pretty sweet!
Done by ARIZONA ROTARY ROCKETS - www.azrotaryrockets.com
Setup comes in Black, Red, Blue, and Silver... I chose blue... because well... I like blue?
Used with a Mallory Reg - pretty nice setup IMO.
There is no movement in the lines, they will not crack or dry out ever, they will not rub through any other lines or wires, this is a system that will last like the OEM setup.
Consistent fuel pressure. The way we have the inlet split to both primary and secondary will ensure consistent pressure. A typical fuel system run serial could potentially see a pressure difference between the first and the 4th injector. Serially there are never more than 2 injectors in the setup to reduce this possible risk.
Perhaps in the future if anyone is interested in a similar setup then I would suggest contacting AZRR.
I just wanted to show it off to a couple of you fab turds haha, it is one sleek setup IMO with a lot of potential and benefits.
These guys are coming up with designs left and right... glad to say I'll be using this setup!

I'd question if this is safe?
All the literature on aluminum (it looks like Al?) hard lines is that it is not recommended for fuel injection.
Even the Russells stuff, which is rated to250psi, explicitly states it's only for carbs.
Why?
Maybe the higher pressures and pulsation actually work harden the aluminum like to the point it'll fail?
I've always wondered...
It definitely is a LOT cheaper than SS AN hose!

It's perfectly safe. As the design was crafted in conjunction with a well known fuel / performance shop here in Arizona. THe company does a lot of custom fuel work and pump designs etc.... as well as cleaning and all that stuff. Rest assured the system is perfectly safe.

Good question, as you mentioned the line will with stand 250psi, as far as the statement about "only for carb use" I could not find this statement on the Russell's site, either way, We have Fuel system engineers from a notible fuel system company that is partnered with us, to assure us that this system will not fail. I think that the point behind the "carb" statement for some manufacturers is not to use this for the whole system from pump to rail, pretty long tubing, we have used this in short lengths that will withstand more than we can throw at it. Many fuel systems from hot rod builders to oem build high pressure systems using this aluminum line. One other cool thing about this system is its fuel distribution, we split the feed and t the system for front and rear fuel distribution giving a even and consistent pressure to each "bank" of injectors if you will.
Oh, check out this http://www.russellperformance.com/mc/fuel/lines.shtml in fact if you read there high lights of the aluminum line you will see they in fact say this can be used in just about any fuel system. Really there whole statement is a bit misleading. I think they just want to sell more ss line.
Thanks all, and thanks Darren for posting this, yours will be ready in a couple of days

And I hate to say this but will the rotary even last that long to worry about rubber hoses cracking? lol To each his own, but this is a pricey setup IMO.

I believe it is relatively unsafe to use aluminum hard line as a fuel line because aluminum tends to harden with "use" and form cracks. The fuel lines can vibrate and this can cause it to flex and harden over time. Eventually, cracks can form and failure can result in disastrous results.
The recommendation is to isolate the hard aluminum line from vibration and movement.

I know the problem with work-hardening with aluminum, so this is why I shy'd away from it.
I just got a shitload of -12 fuel line, so that takes care of that problem.

Here's what the final damage came out to be...
A little over 130 feet of -12 SS braided fuel hose for under $200 shipped to my door in Hawaii.
Can you really complain for that price?
I've got an SX fuel pump sitting in my room, and I didn't realize this thing flows like 120gph.
That like enough fuel for around 800hp!
The -12 stuff might actually be needed for a pump like this.
It's all basically going to go on the 20B car...

Says its rated to 250psi.
If your fuel system exceeds that, then I just don't know what to say.
