    Question Engine Compartment Body Holes and Plugs

    I need a little help to ID these holes in the engine compartment, what goes there and how to plug if not used. Body is a 1970 911.

    1. Pass side engine compartment, front most hole. What goes here? A/C lines? I'm not installing A/C. Is there a factory plug? What part number?

    2. What is this tube for? I was told it might be a connection for the intake "pre-heat" hose. I plan on running webbers with K&N filters so I'm guessing no need. Is there a factory plug? What part number?

    3. Driver side engine compartment. Is this for a factory fuel line? If so, I would guess there is not a factory plug. What do most people do for plugs without factory options? Hardware store?

    4. These 3 holes behind the engine compartment fuse panel. I think I found the factory plugs. Do you install to the firewall from the engine bay or from the outside? Do you use any sealant? I was going to use a little body dope around the lip for safe measure. I would think that would be enough.

    5. This hole is very similar in size and placement to #1. What goes here? Is there a factory plug? What part number?

    Any help is much appreciated. Thanks.

    Thanks Ed. That confirmation helps. Does anyone have a comment on proper direction of plug install and sealant? Probably overkill but it would be nice to do it the same way as the factory... Thanks.

    They were just plastic plugs shoved in the holes.
