Topic: 1976 and 1977 Vacuum line differences

[gjdls95]

Anyone know what the differences are between '76 and '77 vacuum lines?  I found the correct color coded vacuum lines for a '76 but the company doesn't have a kit for '77, can I use the kit for my '77 or no?

Also, does anyone have the vacuum routing for a 1976 T/A they can send me?  I have the restoration CD from Hitman for the 1977, was thinking of comparing the diagrams.

Thanks!

Please share where you found the 76 vacuum lines.

Anyone have a '76 vacuum diagram to share?  What are the differences in vacuum lines between '76 and '77?

The last I checked with them, they didn't have them in stock, and had no idea when they might get them.  Do they have them now?

I was just looking at that last night for my 77.   I to would like to see the 76 schematic.  my guess , they are really close to the same.
may need to find out if they can get the tubing in roll's and not pre-cut.

The vacuum schematics are in the service manual

I have the 77 service manual but not the 76, thats why I need to see if someone has a 76 they can upload.  I checked with them today and they no longer carry the kit for 77 just for 76, thats why I am checking to see if I can use the 76 for the 77, possibly small differences??

Thanks!  It looks like there is a EGR backpressure transducer on the 77 thats not on the 76 and the check valves are on a different line for the 77 than on the 76.  A few other line changes from the ported valves but all in all it may be pretty close.  I guess it depends on the routing on the 76 as if the EGR and ported valves are in similar locations than the lines would probably line up fairly close.

Can someone repost the 76 455 schematic? Haven't found a shop manual yet for my new 76 - took the shaker and air cleaner off and found several dead end lines - Runs pretty well so I'm not overly concerned but I would like to sort it out!

I can post a schematic for you...is it an auto or manual trans?
California or 49 state car?

Here's a good manual to have:

Forgive the ignorance but I have the Autozone lime diagram.

One line from the aircleaner goes down to the choke stove - where does the other from the intake of the air cleaner go? Mine was not connected.

Also, where is the eye valve and actuator? I can't locate that line at all.

I meant where is the EFE valve and actuator?
