Hey all-

I have an LS3 fuel rail with injector clips and am getting an LS1 manifold. Can I use this rail and what injectors would I use?

This rail does not have a fuel regulator on it like the ls1 rail typically does I believe

Thanks
Andrew

I'm looking for the same answer,but that is a dampener on the stock LS1 rail-not the fuel pressure regulator.

I discovered that salemetro on here managed to install an LS3 rail on a fast 102 intake with 1/4 spacers. I think the fast 102 is an ls1 style intake? Can anyone verify?

I did it with stock injectors, just used conduit hold downs as the mounting tab locations are off a hair, or you can use fender washers. Spacing the injectors up is necessary too think I used 4 washers under the rail to lift it

Without some creative mounting hardware, the LS3 rail will not fit an LS1 intake. Also, a FAST 102 uses LS2/LS3 rail mount spacing, which is not the same as the LS1 rail mount spacing. Again, you can make it work with creative hardware, but you'll unnecessarily screw with your injector angle. Get an LS1 rail and be done with it.
