1967 Continental Vacuum Questions

Hi Bill-

I was hoping you could clear up a few things up for me. I am a doing a restoration/rebuild of the engine and engine bay area of a 1967 Continental and am having some issues with routing a few of the vacuum lines. I have a shop manual and took good pictures of the way they were routed but unfortunately the car has had some "modifications" in the past. I will try to be as brief and clear as possible.

I currently have the door vacuum (1/4" w/check valve), the automatic temperature control vacuum (1/4" w/check valve) and the speed control vacuum (1/4") routed from the plastic tee.

1) Where does the 1/4" transmission vacuum line hook up?

2) A 1/4" vacuum line freely came out of a hole in the firewall just above the passenger side vacuum connector. What is this?

3) There are two (2) vacuum lines coming out of the firewall above the driver's side vacuum connector. One is 1/4" and the other, maybe 1/8". What are these?

4) in the shop manual (reproduction) on pages 17-20 and 17-21 are schematics for door lock vacuums for early and late production. I have the early, but my question is regarding the main 1/4" line just after the check valve. The schematic shows a tee but does not clarify where the line runs?

That's what I have for now. Any help would greatly appreciated!

Thx -

Hello Gordy -

Without any photos of what you are seeing I can offer the following based on your description.

1) The transmission vacuum line plugs into a small nipple at the brake booster inlet/check valve.

2) This could be the rt. w/s washer jet supply hose or if the hose is close to the center of the firewall or the hydraulic wiper vacuum actuator hose.

3) This answer will be a guess but at this location under the brake booster there are three vacuum ports arranged in a triangle shape. These are for the ac/heater controls. Any small hoses that are passing through the firewall could also be w/s washer hoses.

4) This tee possibly could be a connection that was used in the very early production automatic locking door lock feature that FoMoCo was trying to introduce. The doors would automatically lock when the vehicle reached approximately ten Mph. Many of these malfunctioned and locked at very inopportune times and upset owners. This feature was discontinued at the factory very soon after introduction and the Lincoln dealers were advised by special bulletin to disable this feature on any Lincolns that were at the dealer for any type of vacuum door lock repair. This tee could more likely be a vacuum supply for the power trunk release and is not part of the power door locks at all.

You have indicated that the under hood components may have been modified and therefore the above information is the best that we can provide at this time according to your observations. We hope that the above helps.

1963 Continental Fuel Line Questions

Bill -

I have a 1963 ready for restoration and it has a fuel line leak.

We are going to replace the entire fuel line from tank to pump but noticed there is a second line approx. 1/8" in diameter coming from the fuel tank
following exactly the same path as the fuel line.

As the fuel line comes out of the drivers fender well in to the pump, this other thin line is there next to it but not connected.

Is this second line a vent? Can I cap it or not?

Thanks for your answer.



Hi Tony -

The engine originally would have had a fuel pump with three ports and the second line from the fuel tank was connected to the third port. This design with the third port and the second line to the tank was developed by Ford engineers to reduce or prevent the possibility of fuel vapor lock on these engines by re-circulating warmer fuel back to the tank and therefore providing cooler fuel in the lines near the engine during hot driving conditions. Some engines (but not all) of this type with the two port fuel pump located on top at the front of the engine are known to suffer from fuel vapour lock under certain driving conditions. Many of these three port fuel pumps when they eventually failed were replaced with conventional two port pumps and the second line to the fuel tank was capped with no problems. Some owners found it necessary however to revert back to the three port design. If you are restoring your Lincoln for show or possibly for a serious "judging" event you will want to install a three ported fuel pump as you will lose points. For more information and availability on the original style pump contact Chris, George or Al at Lincoln Land and we will help you decide what might be the best choice for you.
