93 intake on a 94 Will a 93 intake &&& fuel rails bolt right on to a 94? I have both a 93 & a 94 lt1 and I notice vast differences between the 2. The 93 has different style fuel rails and doesn’t have the crossover rail like the 94 does and on top of that the actual fuel lines themselves are a little different. If there are any other details I’m missing let me know.
thanks,

The regulator is attached directly to the return line (5/16”) on the 94, at the rear driver’s side corner. Lines on the 93 attach by the driver’s front corner and the regulator is on the passenger side toward the rear of the rail (still in the return line path). The vacuum line from regulator to manifold vacuum barb would be shorter on the 93 but work exactly the same.
The 94 lines will be longer since they were made to attach at the rear corner and making them do a u-turn back the front corner would be problematic. You can get the lines from a 93 and use them. All years route inlet, return and evap/canister lines down the driveshaft tunnel from the tank alongside the rear brake line feed. The soft lines you see in the engine bay attach to the hard lines just forward of the tunnel brace, and make an outboard turn to just inboard of the pinch rail. There is a plastic guide/retainer that feeds them from there up the driver’s fender well behind the fender liner and inside the fender.
if you had all the parts and were bored enough to do it, it would work fine. IMO, not worth the trouble if you don’t have everything in hand to make the swap.
And yes, the 93 had 22# injectors whereas the 94-97 had 24#.
