I noticed there's a directional arrow on the solenoid and there's a diagram on the hood for the purge system, if anyone gets confused.
I was able to get it sorted today. I was hoping to find a bolt for the nipple on the manifold but had no luck. I even tried a big industrial fastener place.
The thread pitch is 0.90mm and I believe the diameter is 8mm? Might be able to get it online.
But Autozone had some nice nipple caps.
Good stuff. Happy to clean up the engine bay a bit and remove something that could cause issues.
