Will LS2 injectors fit into a LS1 fuel rail I am wondering this because i picked up a fast 90mm intake manifold today, i already have the ls1 orings for the injectors, now to save me the headache of bending the stock fuel rails, can i buy some billet ls1 fuel rails and just plug my ls2 injectors into those? Will my fuel line fit right into the fuel rails and my biggest question is will the top of the injectors fit into those new ls1 fuel rails. If they do not then i need to buy ls1 injectors what size should i go with to match the factory ls2's i have, any help is very much needed. Thanks - JW

The lower part of the injector is larger on the LS2, so the injectors likely will not fit into the holes in your intake. I don't know of any easy fix off hand, but it can always be done.
FAST should be looking into a solution for this.

No the problem is fixed on the bottom end by putting ls1 o-rings on the injectors, they slide right into the fast then. But what im looking for is to buy probably some billet ls1 fuel rails and mount my ls2 injectors in them (BUT WILL THE INJECTORS FIT) and with the ls1 fuel rails the holes should line up just perfect to bolt the rails down.
