I just discovered that a vacum hose, running from my driver side fuel regulator, is disconnected. In the image below, you can see where the broken connector and the hose is open.

Question is, where should this go? I put a new vacuum hose from the back of that fuel regulator to an empty connection under the "spider," right next to where the line from the other fuel regulator ends up (after connecting with the fuel damper in front).

I suspect this isn't totally correct because of the broken connector in the old hose. Does it connect with the fuel damper on the other side?

Thanks for all the help.

 

Sorry, its a 1982 AT.

 

k...that goes to other "Fuel Pressure Regulator"....If I am look at the picture correctly...the one on right is connected to that vacuum hose that runs to the fuel pressure regulator on the left....

There are two Fuel Pressure Regulators on the right-side of the engine and other on the left-side of the engine.

Looks like from your picture the vacuum line on the right-side is the only one connected....

Also you are going to get lots of feedback to replace all of those vacuum lines...Roger can get you a set. I just had a non start issue with my car that was because of freaking vacuum line leak....Those vacuum lines on your car are orignal...

 

Thanks, risaac928, I've routed new vacuum hose between the fuel pressure regulators, up to the throttle body, and up to the fuel damper. I'm slowly but surely replacing all the hoses. Some electrical stuff has interrupted that plan recently though.

Funny thing is, the car doesn't run appreciably better or worse now that its correct. Its still got a little lope in the idle that I was hoping this 'vacuum leak' would fix. What did this fix? Maybe I should expect better gas mileage?

Also, thanks PO, or PO's mechanic. I wonder what else he broke and then ignored or didn't notice.

 

Lol....yeah man...welcome to the club. Vacuum lines need to be replaced. This car relys heavily on vacuum lines. You don't want to be buying expensive parts when it turned out to be a vacuum leak.

As far as that loop, you may have to live with it, if it's not that bad. Mine has slight hick up. Mind you were talking cars that are 30 years old.
