Does anyone know if the return fuel rails from a 4.6 Mercury Cougar will fit on a Mustang 4.6 with the return fuel system?

As long as they are off a 96-7 T-Bird or Cougar they should work. I have a '94 Cougar with a little work done to it.


You can see the fittings in the pic. Are they were yours are located?

Unless yours absolutley need replacing they should be good for at least 350 hp. That's what I've read in 5.0 anyway. With the mods listed I would have to ask why are you wanting to change out your fuel rails?

They don't need replacing, If you didn't know, the 98 fuel rails will not accept an aftermarket adjustable FPR because the stock one is welded to the rail. However the 96-97 4.6 fuel rails will accept one. So that's why I was wanting to change the rails out sometime. Being able to change FP is a good thing to be able to do.
