Re: vapor lines
This should help
If you dont have a factory assembly manual i highly recommend getting one. After all that spaghetti mess back by the tank theres only 1 5/16" vapor hardline that runs to the engine bay (along with the fuel delivery hardline) that connects to the charcoal canister. Plus the brake line. Last edited by SeventyOne; 11-07-2020 at 04:04 PM. |

Re: vapor lines
I do have a factory assembly and I have the same picture . What I don't have is the lines going from the back to the front. 850. 00 dollars inline tube put a hole bunch of lines in a large box. (A real mess) The gas line I got the brake line I got. Their was another long line about the size of a brake line that goes from the front to the back with yellow caps on it don't know were that one would go. (May be they just but it in the box by mistake) The other 3 lines look like they get put together and run from the front to the back for the vent to charcoal canister.
