Welcome, Here we have a Tuned Port Injection, Fuel Rail With Regulator. & 4 Mounting Bolts With 1 Fuel Line Bolt. This is a Fine Beauty, Pulled off of a Running 1991 Chevy Camaro. With Automatic, 5.7 350cu.in. Engine. This IS From a Speed Density Engine. With Out a Mass Air, or the 9th Cold Start Injector. Injectors are clean and could be installed and ran the way they are. However I would recommend getting them Flow balanced and cleaned at an injector shop, just my opinion. New "O" Rings for sure, though will be needed. This is a clean fuel rail. just bolt and go here. Fuel lines are in great shape. There is no kinks or flow restrictions in them. The threads are also in good shape. As are the Fuel Regulator bolts. This will work on 1989-1992 TPI applications. May work on many other years, please look at the close detail in the pictures and make sure this is what you are looking for.
