Carburetor vacuum lines routing diagram needed

Looks like you have a vacuum diaphragm for the cruise control, so I am attaching the diagram below for the cruise control.

Also, I am attaching a clean copy of the diagram you have on the vehicle.

Basically, the way to figure these out is pick a line and follow it through the diagram in order to keep them straight. These things were a nightmare if you had some lines come off.

However, we need to just make sure the components have a connection to the vacuum source which is the intake. This is what those multiple connection points are used for. So instead of daisy chaining or having a lot of splice connectors, you just run a vacuum source to these multiple line connectors and then you can connect each component to it.

Hopefully that helps explain what that is.

As for the other picture of the part labeled 64249, that appears to be a check valve that would only allow vacuum to flow one way and is meant to hold vacuum.

Did you disconnect the lines for the transfer case as well?

That is the carburetor. Those are the different lines coming off of it going to various components.

Basically, they liked to use the carb to access intake manifold vacuum as it is an easy access point.

More than likely someone has altered this over the years so you may have to undo what some people did but the key thing is to make sure there are no open lines because that is an instant vacuum leak, and it is going to cause the engine to run poorly.

I would think this is a vacuum leak before a fuel filter issue. Both would create a lean condition which would result in getting it started with starter fluid.

So, I would stick with the vacuum leak issue and then we can figure out a fuel issue if needed.

Yeah, that is fine. Clearly, they may have to be addressed again in the future but that should work to hold it in place.

The idea of this cover is given you adjustability to the choke spring for the different seasons so if you need to adjust it, you will have to cut them and then reattach them.
