    EFI Vacuum Diagram

    Hey, does anyone know where i can find a vacuum diagram for the 86-87 efi?? I am in the process of an EFI swap and im scratching my head over what goes where...I heard the diagram is on the hood of the cars so i went to the junkyard and found an 87 lxi and tried takin the sticker but no luck with that, those things are like welded on...Anyways, if you guys know of anywhere that may have a diagram, it will be very helpful...I don't wanna get this all done and watch my fuel guage drop a mile a minute cuz i forgot the fuel pressure regulator vacuum line....mmmmmmmmmm 40 psi of fuel, haha
    if junkyards didn't exist, neither would my car...

    Use the Honda manual. It's available in pdf format and is linked in a sticky on the forum somewhere.

    The EFI fuel pressure is 37 psi so 40 wouldn't be too bad.
    No projects. Life consumes my time and money.

    IF you just need to get it running, just connect the MAP sensor to the throttle body on the pipe sticking out closest to the adjustment screw - it is really all the car needs to run. After that, work on the rest.

    i checked the online shop manual, and same problem, its the vacuum diagram for the newer manifold and doesn't help me much, all i figured out was the fuel pressure regulator, any other ideas

    here is 86-87 EFi vacuum layout.
    you may want to save this one since you don't have real Shop manual.

    While sort of on the subject of shop manuals: has anyone found differences in our cars and the Pauls shop manual? I mean, isn't his for the European Accords, and are there differences that anyone has found?
