hey yall i got vacuum lin e question
1978 chevy blazer crate 350 GM
so i changed my EGR valve just to rule out i have a bad valve. i also changed my EFE TVS valve a whiule ago so ive come to the conclusion by looking at my service manual that my vacuum lines must be totally backwards ....but my thing is it passed smog befor so im reluctant to switch it to the way the manual says.ive got two outlets to my charcoal canister blocked off. but in the manual it has lines going from all 4. the one thing that confuses me is that in the maual it says to air cleaner ("G only")what does that mean? im just a little confused because i have **** with 3 way splits to stuff the re routs back to the EFE TVS valve anyways my question it what does all except "G" means i cant find nothin in the service manual that explains that .im looking at the vacuum hose schematic for a v8 350 cid -ld emissions it looks like my vacuum schematic because its the only one with the dts&efe tvs valve with 4 outlets on it ..im ramblein on but my questions are what does that to air cleaner G only means ans should i go ahead ahead and go by this schematic even though mit passed smog befor even though it still runs ****ty?
