Mike:
Your stock rails will hold up to a max of 500 RWHP
at the very most.
Thats only W/ a big boy pump though.
Now 36's will be good up to 430-440 rwhp and no more. I know from personal findings. So there for I have set of them for sale only 2K miles on them.
What is your exact current fuel system?? Lines, filter, pump, ect??

the current fuel system is 30lb inj, 255 in tank, stock fuel rails plus lines. I think i will keep the stock fuel rails and jump to 42lb injectors.
What kind of problems were you running in to?

Actually I'm running stock lines and rails, fuel pressure fell off @5500 rpm. That still dynoed more than that at the wheel ![[Eek!]](eek.gif)

ya im looking to push this thing to about 440rwhp, and about 6,800 rpm shift points.
I do want to make sure that these stock rails hold up, and if not can I just buy the rails that bolt right up the lines?

GR40lx: Of coures you could see more power that I listed but what I listed was safe power where your "fuel does not drop off".
YOU NEVER WANT YOU FUEL TO DROP OFF!!
Mike your pump and lines should all be just fine.
Your rails will be fine too as long as you use those 42lb injectors your set up is sound Bro ![[patriot]](graemlins/patriot.gif)
However if your looking to get a set of 1/2" rails, Aeromotive makes a real nice bolt on rail.
Dude if you buy just the bare rail W/ no lines a nd fittings then I could hook you up W/ all the special fittings a and lines they sell to make it hook up directly to your factory lines.
I bought the Aeromotive kit that is a direct bolt on to the body lines W/ all the correct special fittings and lines, to find out that I could not use any of it excep just the bare rails.
Lemme know Ill hook you up

anyone know if there's legitimacy to the '94/'95 rails handling more fuel? I was going to sell them, but I'll keep the '94 cobra rails if they hold more fuel than the '86-'93 HO?

I think its the line that connects the two rails that is the restriction and changed on the SN95's. the SN95's also have a larger feed tube from the fuel pump, but it won't fit your fox's connector unless you install a larger one as well. Found this out the hard way ![[Cool]](cool.gif)
