4v fuel rails

schacher94gt · Jun 11, 2011

Hey guys when i build my motor i went ahead and swapped to C heads. I knew that id have to mod my fuel lines but I thought I was gonna have to just bend the tabs straight but instead id have to cut off the whole bracket and weld them to the right place. Anyways my question is if i just pick up a 99/01 cobra or mach 1 will it be a direct fit(are they returnless or return style rails) and also would my fuel regulator be able to be used?
thanks guys

they are returnless! you will likely have to buy some aftermarket rails or modify yours, somehow...

What are you running for an intake manifold?

'99+ is returnless.

It's wicked easy, just cut the tabs off the rail and weld them where they belong.

im running a mach 1 so im just gonna have to cut them, straighten the tabs and than weld them back

yeah man there is actually a writeup out there for it

The writeup I know is actually for an '03 Cobra lower, but it's similar.

Don't worry about straightening the tabs, you'll prob end up cutting the "feet" off the bottom of the tabs anyway.
If you do it right you can even keep the ford emblem........

Try to pick up a set of C-head fuel rails it seems like its the easiest way if you dont have a welder handy and arent the best at welding. It is thin metal and easy to warp. I think I may have a set or 2 laying around if your interested send me a PM

But the C head rails are returnless and B head rails are return style so he needs to modify his stock b head rails so he doesn't have to try to make the c head rails return style. OP, cut off the mounting tabs and have them rewelded to the sides. Its been done many times and works great.
