Stuck Throttle

[Logan Robb]

While out for a Sunday cruise this afternoon, I had a small heart attack when I opened up the throttle a bit and went to let off, only to have the ol girl keep going. Luckily, I was on a straight piece of roadway in a familiar area in the country and pulled off keeping the throttle pulled up with my foot. 

Upon inspection, it appears the main vacuum line that comes from the rear of the carb/manifold to the bottom of the break booster was replaced at some point and was routed near where the throttle arm mounts to the firewall. When I opened the throttle, the hose got caught in the space and wouldnt let the throttle return all the way. 

My question is this-what is the correct routing of this vacuum line so that it avoids the throttle? It was also a little closer to the valve cover than I felt comfortable with. 

I'll include some photos of how it is presently. 

Thanks!

When the throttle was stuck, the tube was on the right side of where it is now. However, this cant be the correct routing as it rubs the valve cover and moved when the throttle is pushed.

Should there be a hose clamp on the vacuum line for the booster?

As you can see, the vacuum tube from the bottom of the booster has been zip tied to the factory mount

Yes there is a clamp

Ah. So it looks like I’ll need to route it further up the firewall and back down. 

I may as well replace this hose as well. Would regular vacuum tubing work or is this a special type? It’s rather thick. It looks heavy duty in your post as well. 

I noticed that your booster port location is in a different spot as well. There has been some discussion around my Bendix booster. I think we determined my booster is from a 63
