So I have a 90' S5 FC3S and I have a pretty big fuel leak. I haven't been able to find it but for now I'm gonna pin it on the FPD. I'm going to test the whole fuel system this weekend and find it for sure.

Anyways, while I have the whole intake manifold off, I was thinking about buying new injectors while I'm at it because these old ones are horrid. I also was looking into getting a new fuel rail so I could bypass the whole FPD situation. Now I probably haven't done enough reading but I know it's there to dampen the fuel pump pulses for obvious reasons.

While looking for aftermarket fuel rails I can only find ones for 13B-T's and 13B-REW and Cosmo motors. So my question is, can I use a 13B-T fuel rail on an N/A?

Like the ones from Full Function Engineering | FFE Store ...

Thanks,

-Ben

 

no, just go with an S4 aluminum primary rail with the mod banjo bolt.
