97 fuel rails on a mach motor help

[97_281gt]

Putting a 04 mach 1 motor in my 97 gt my car has the return style fuel system. Any one know how to get the fuel rails to work on the mach motor don't really have anywhere to bolt down and one of the brackets is hitting the intake and not letting them sit right. Any one have a write up on how to do it I can't find anything on it

I dont think theyd fit since your 4v motor since theyre meant for a 2v intake manifold. I would try to get a set of 96-98 cobra fuel rails since theyre meant for a 4v intake and theyre a return syle.

My cars already has a cobra motor in it the fuel rails mount in a different spot in the 99-04. One guy did it but cutting and welding the mounts different. Just didn't know if anyone else had any ideas. Trying not to spend 300 on fuel rails that will work

I understand you already have the 4v in it, I was under the impression you were trying to use the 2v fuel rails on the 4v motor.

Just for clarity, you are trying to use the fuel rails that came with the motor but the mounts dont line up? I dont understand because they came with the motor. Plus they have no return line so you couldnt use them. Or if you are in fact trying to use your stock 97 gt fuel rails then my suggestion still stands. Perhaps there is someone who has done the conversion and will chime in.

Oh ok now I understand. Unless you can find any info on the swap you might have to use aftermarket rails. Thats crazy the b head and c head motors have different fuel rail designs.

this is for a v6, changing a split port onto a single port, but the fuel rails had to be modified to work from returnless to return. maybe you can do something similar.

Any aftermarket rails can be set up as return style if you plumb them correctly and add the fuel pressure regulator.

Could you possibly explain to me how I've never messed With anything like this before

Man, I swear I had a response in here a couple says ago.

Anyway, the stock fuel rail setup has a supply line that feeds the passenger side, it crosses in the front to the other side, and then feeds the driver side, crosses in the rear and goes through the pressure regulator then out the return. Youll set up the aftermarket rails just like that with the regulator after the rails so you maintain good constant pressure in the rails. Youre basically going to build the aftermarket setup to mimic the stock setup.

Lets see some pics! Search out pics and show what you have. Who knows, maybe truck fuel rails will work, but I gotta see some pics.

Ended up figuring out a way to get it to work for me with out buying rails

Probably not the best way but there in there and they don't move so they will work for me
