Adding an additional vacuum reservoir,
like you can see under the hood of various diesel pickups, might also be a worthwhile experiment.



Just by adding another t-fitting in the line and plumbing it in? The truck has one hooked into the bag of snakes (vacuum lines) and runs right below the windshield. I did find the dodge factory service manual. I'm gonna look into it for testing and operation of the various systems on the truck.
