okay!, quick run down, 89 coupe,2001 cobra dash swap, 97 mark8 engine, still has b heads, 98 cobra intake, with imrc deletes, entire vehicle wiring from the cobra. so it's set up for return-less fuel. i'm trying to stick to stock parts here to keep cost down. that is why i was asking.What exactly are you trying to accomplish?
The 2 rails regulate pressure in different ways,
and require completely different fuel systems,
and possibly different engine control systems.
that is the exact answer i was looking for. thanks!I can give you a few things I learned 2 years ago.
The fuel injectors are spaced the same width apart on the 96-98 Cobra as the 99-04 Cobra. It doesn't bolt on, because it bolts on completely different, but it does mean that brackets can be made to make it work. You won't find a "kit" for that, but brackets are easy compared to creating a custom fuel rail from scratch. It is also a lot cheaper than AN fittings and hoses for billet rails.
The 99-01 Cobra fuel rail is the same fuel rail as a 03-04 Cobra fuel rail, so that increases the "supply" of used factory rails for you to find..
The fuel supply line in a return-style fuel system has the same exact fitting that plugs into the fuel rail on a returnless system. Since the 96-98 Mustang has its fuel lines on the passenger inner fender, it could plug right into the returnless rail. You could swap in a 99+ gas tank, wire it up and keep it simple. You wouldn't need the return line, so you would have to decide how to dispose of that.
