Replace knock sensor. Does the injector rail pull up once

Customer Question

Replace knock sensor. Does the injector rail pull up once the two screws are moved? Do you need to have an injector o ring or replacement kit, or if you're careful to pull the rail, can you slide the rail back after service of the sensor and/or harness. Can you really get to the sensor through that little opening?
JA: Are you hoping to fix this yourself?
Customer: Yes. I have the parts already.
JA: Great! What have you tried so far?
Customer: Removed the cover, intake manifold, cables, two screws below the rail, injector electric couples. Can see the little sensor between 4 and 5 barely, and it looks like the harness is not connected. PO325 error. AFTER the battery was disconnected for a few hours, the engine light went off, then came on with a PO443
JA: Lots of things can cause problems with the battery. The Acura Mechanic will know what to do. Is there anything else the Acura Mechanic should be aware of about your Acura?

Yes, the fuel rail will come out and when you install it, just put a little WD-40 on the seals so that they slide in easily.

I pulled off the top of the intake throttle assembly and the spacer. Then, the rails are aligned with the top of the 'manifold'. The Knock Sensor can barely be seen between the ports. Hard to see if it's just the harness or more. Wondering if just pulling the rail will be enough to get to the sensor, or is there more...such as removing the manifold down to the cylinders to expose the block.***@******.***. Thx.
