Skunk2 intake on h22a swapped 1994 Accord ex (airline diagram?)
What’s up guys I got a 1994 Honda accord EX with a swapped H22a.
I got it on a trade for some paint work and couldn’t be more stoked!
proSeries intake skunk carb sitting on skunk two suspension ,jasma headers, mishimoto rad ,full apexi exhaust. Needless to say it’s got a little money in it but I’m stuck with an issue a lot of the wiring was hacked up I seem to have gotten that plugged up (messy but plugged up)
I am stuck with vacuum and coolant lines as you can see in the pictures I have less rubber hose then I do male ends on the intake.
can anyone help with what goes where and why I can just block off.
did the best I could with pictures .
anything helps !

Re: Coolant/vac lines??Skunk 2 intake on h22a swapped 1994 Accord
The hose with the purple arrow pointed to it is the fuel return line. It plugs into the fuel pressure regulator, which you have circled in red in another picture. You will need to secure it with a clamp. The vacuum line on top of the fuel pressure regulator gets plugged into the closest vacuum source on the intake manifold.
In the last photo the item you have circled in purple, closest to the fuel pressure regulator, is the PCV valve. You will need to run a vacuum line from it, to the larger diameter vacuum port on the front of the intake manifold. The other item circled in purple is a vent that needs to be connected to the intake tube/pipe. It can be left open but it will make a mess so optionally you can put one of the little mini breather filters on it if your intake tube doesn't have a spot for it.
"No clue" is a coolant line that needs to be reconnected to the bottom front nipple on the throttle body.
The thing connected to the canister is just an emissions thing. You can unplug the sensor and just leave it unhooked. Your ECU likely can't control it anyway since it will have be changed for the H22.
The item in the first picture is the Idle Air Control Valve that's been relocated due to the manifold swap. The line that's unhooked is one of the coolant lines that run to it, and if I had to guess I'd say it's probably going to connect to the nipple on the bottom backside of the throttle body.
A bit out of order but mysteries solved. That is one janky looking swap. Be sure to secure all the lines with clamps or zipties for the smaller vacuum lines.

Janky is an understatement. But I appreciate your response, I did get it to start and run but idles very rough, something I’ll have to look Into. Also ha a slight fuel leak from the rubber line that mounts to the fuel rail.
Definitely needs some work but it’s worth putting time into! Thanks again!
