Welcome to the Ford Six forums, here is some info on the LOD system that maybe of some help to you. First off a stock Load O Matic (LOD) Distribitor also needs to have a compatable or matching Carburator to work correctly. There are severial like the Holley 1904 & 1908, Autolite 1100, and some of the 1940 Holley replacement carb's. This system is simple and works quite well when everthing is maintained, it's suitable for a totally stock early engine and for those that want to keep their 1960 to 1966 - 7 cars or trucks all original. See below link for more info on the parts needed as well as how a LOD system works.

How to make a replacement for a damaged or missing vacuum line for the Holley 1904 and Autlite 1100. The Holley and some other Carb's that Ford used has a threaded port that the Vacuum line screws into. On these carb's a steel line is used with a compression type fitting, these fittings are the same as is used on a natural gas water heater pilot light. This is the compression fitting that fits the threaded hole in the Holley carb (see in link below). They should be available at many hardware stores or your local Auto parts or NAPA dealer too.

This above fitting are made for use with a 1/4 inch Steel or Aluminun line if you don't care about its originality, stock Ford used the steel line. If you have the old vacuum line for use as a pattern you can use a tubing bender or by bend the line hand to match the orginal bends in the old line. If you don't have a patern you will have to free form fit it to your engine. To install thread the compression fitting into the Vaccum Port and but leave it somewhat loose next push the 1/4 inch line into the compression fitting until it bottoms out then tighten you up the compression fitting. On many of the the LOD Distribitors the same compression fitting is used to connect to the stock vacuum canister so you may need to get two for a stock system. If you are going to use or already have a later Distribitor then run the line down near the Distribitor the use a short piece of rubber hose to conect the line to the Vacuum Advance. On some other carb's Ford used a flare fitting for the vacuum line conection into the carb in these cases a brake line of the right size can work or if you have use of a flaring tool you can also make it from scratch.
Mod's to the LOD
There are a few things that can be done to make the LOD system work a little better its a good system for a stock engine or were you need to keep it original as in a Restoration project. First make sure the vacuum canister and the carb's SCV are in good working order. The MoPar electronic control box can be added for a hotter spark and better running and the points will last practically forever. The Pertonix Ignitor unit with a better (Hotter) coil too, is another way to eliminate the old points for a little less Maintance and better running.
By the way Champion Carburetors has a new replacement carb this is an updated copy of the Holley 1904 that can also be used to replace a 1908, the Holley 1940 or an Autolite 1100. these are brand new carb's that don't have the SCV on them but they can be used both for a stock LOD system or a newer Distribitor (see below link) also you can check with Vintage Inlines for this carb.
