Question 78 Elcamino vacume diagram

I can't find a good vacume diagram for my 1978 Elcamino. If you can help please email @ "bearjmh@yahoo.com" Thanks

Have a look at the underhood emissions sticker.

If it's gone, try http://www.cybrrpartspro.com/Manual%...elLookup.html.

If you strike out in both cases, try the local public library.

The engine size would be a colossal help as well....

An old Motor or Chilton book (as Knuckles stated in the library) should help out.

Barring that, the OEM service manual from GM is the best bet.
