Hi, I am new to this site but would like to ask a few questions. I have a 1988 Toyota 4Runner with a fuel injection 4cyl. engine. The engine has just been rebuilt and i'm attempting to install it. The job is almost complete however there are a few lines I am uncertain where they connect. The first is the line that goes to the egr valve. I'm fairly certain this is a vacuum line but where does the other end connect? Also, there's a component near the egr valve, I think it's a fuel pressure regulator. When the engine tries to crank,fuel comes out the bottom port. It also has a port on top. Where would these two line attach? I have searched for diagrams online and have a repair manuel but still can't determine just where these lines connect. I also have a few more lines but will only list a few at a time to help eliminate confusion. Any advice or photos would be greatly appreciated.
