I have created some vacuum diagrams mimicking the assumed original labels found on the forum. I did my best to add the part numbers installed and/or used in my FZJ to route the system without a CEL or hard starts. I wanted to create a simple reference for those who will want to do it in the future or diagnosis.
If there are any mistakes - please do let me know! I have been running this setup for about 3 months and ~1,200 miles without a CEL.
During my head rebuild, I removed the EGR system on my US 1997 Land Cruiser equipped with the 1FZ-FE and OBDII system. I wanted to keep the VSV in place and prevent any CEL. There are quite a few posts talking about removing all the under-intake vacuum lines and then later adding in the fuel VSV.
My truck's under hood was modified so I did not have an OEM vacuum diagram to make the process streamline, but thanks to MUD I was able to find the relevant information I needed.
Shoutout to these threads:
Disable the EGR system the (mostly) Toyota way (I am using a 4.7k resistor)
Fuel Pressure VSV Delete

Update Routing with Fuel VSV:
