Floridastang 13 Report post Posted August 30, 2015 I am trying to find the source where I can get the most vacuum form my Cleveland motor. I want to run vacuum from that source to the vacuum canister for the operation of my air-conditioning system. My current tap does not provide enough vacuum to operate the motors. Thanks for your help. Quote Share this post Link to post Share on other sites
Ridge Runner 1,113 Report post Posted August 30, 2015 i believe the vacuum originally came from the back of the intake .The nipple that goes to the brake booster should have a small nipple for vacuum to the dash controls and to the canister . Quote Share this post Link to post Share on other sites
Ridge Runner 1,113 Report post Posted August 30, 2015 A little correction ...the vacuum comes from the back of the intake to the canister and from the canister to the inside dash controls . Quote Share this post Link to post Share on other sites

Here is a video on checking it. https://www.musclecarresearch.com/content/testing-ford-vacuum-canister Edit, if your problem is due to a large cam and just not producing enough vacuum at idle Hella is just one company that makes vacuum pumps for heater/ac controls, the Hella is like $130 from Summit.
