What year is your engine package? I am guessing you have the VST style injection with MEFI 1 ECU and utilizing the Keihin injectors. The other style Manifold typical in 99 on up Cool Fuel systems utilize the Weber style injector.

I have both styles with the appropriate fuel rails.

I take it the other style manifold has the vst pump that mounts behind the plenum. If that is the case I have the entire setup still mounted in a boat but needing a new home. Randy

For future reference the difference is in the injector port the Keihin style is counter bored, and the boss on the lower for the 8 inch bolt

Thanks for the heads up tunertech, I will have to pull the other setup off of the engine. Randy
