i, I saw from one of your old mails that you have a Ford I6, and a Holley 1940 carb. I have a problem finding out where the vacuum lines go to/from. Can you help me? I have the Holley Guide for 1940 and 1945 carbs but it does not show the vacuum lines for the 1940, only the 1945. I have ordered a new gasket rebuild set (3-477 from Holley). My problem was that I could not start the engine (well, still can't), and I think the problem is the Carb. For your info, it has a double vacuum distributor, fon't know if it's a load-o-matic. Thanks Jes
