Swapped an F23A Engine into a 94 Accord M/T. Didn't want to make this post but I can't seem to find too much help online. (Kept F23A Manifold)

Having a hard time routing the Fuel Lines. Does anyone have a diagram of the fuel system on the F23A? Or intake manifold vaccum lines?
Where do the two hoses from the IAC Valve connect to?

 

You can just use your stock fuel rail/injectors and your factory fuel lines will fit fine. For the vacuum lines it's basically just extended whatever you need to make it fit. The brake booster line will fit without mods. Others may need an extension or to be cut back. You don't really need any line on any specific port. Just as long as something that needs a vacuum source gets one you will be fine.

If you are OBD1 you will need to get an IACV adapter to run a 2 wire IACV on that intake manifold. The lines connect to coolant sources.

 

Not very helpful, I know what to use it's a matter of routing the line to the correct spot. I already have the 2 wire IAC bolted on, and are both passages for coolant? (On the2 wire iac)

Having a hard time routing up my fuel system.

 

Well if you were more descriptive it would be easier to be helpful. You're basically going "where does all this crap go?" Nobody has a clue what specific lines you're talking about hence why nobody else has chimed in. You either need to be more specific and post with pictures of what you need help with or go google both service manuals and figure it out for yourself. The service manuals are readily available for both chassis' and have all the information you're asking for.

F23A into a CD chassis is a super easy and simple swap. There are only two fuel lines and I already told you that if you use your original F22 fuel rail and injectors the factory lines that your car originally came with will work. The feed will be the line that connects from the fuel filter to the fuel rail via a banjo bolt/stud/nut on each side. The fuel return is just a piece of hose with a couple of spring clamps that connects the exit of the fuel pressure regulator to the fuel return line on the firewall.

What specific vacuum lines are you needing help with? The F22 manifold has a little vacuum block on one side, whereas the F23 manifold does not. Just find an empty vacuum port for everything that needs a vacuum source. If you run out of ports go to autozone and get a T fitting assortment.

Again, both of the lines that connect to the IACV are for coolant. It simply makes a loop to warm up the IACV as the engine warms up. I believe one port connects to the thermostat housing and the other connects to the throttle body or rear water crossover pipe.

 

Thanks for the information, I jumped the gun. It was all easier to route than I had thought. I took diagrams from both cars (98-02 Accord & 94 Accord) to help me finish routing the lines.
