Where is the other end attached? Older hondas would have a number printed on the vacuum line in white. Take a look at your vacuum line to see if it has a number.

Unfortunately no number. It’s just a long hose and I have yet to find where it goes

Another thing that might shed light is whether the engine swap was identical? Meaning was the donor car the same year, same transmission, same version, etc?

Yes came out of another accord 2.4 k24. It weird because it’s two hoses next to the fuel rail. One goes to the intake and the other long one I don’t know yet

What I meant was just saying K24 isn't enough information.
Donor car 2003 or any other year?
Donor car automatic or manual transmission? Your car auto or manual?
Your car vs donor car was LX, EX, or what version?

Little things like vacuum hoses can change from one version to another; in particular the automatic transmission cars have a vacuum-operated engine mount in front (#9 in the picture). Manual cars use a similar-looking mount without any vacuum tubes or vacuum solenoid valves.
