just get rid of all the lines except for you pcv valve, brake booster, vacuum advance and plug the rest of the lines off
Go and buy a good manual for your year and model truck. Sometimes, there is a vacuum diagram under your hood on a sticker
When you accelerate it probably does not quit blowing but rather blows out the defroster vent. This would indicate a vacumn leak or possibly a bad vacumn check valve. The check valve is located in the vacumn line that goes through the firewall somewhere between the firewall and where it connects to the engine. Check the vacumn with a vacumn guage (pump) in line going into the dash for vacumn leak. Hope this helps. Keith
It is not in the factory repair manual. They refer to the diagram in front of the radiator on a 2000 Dodge Ram 1500. It is a very basic diagram and leaves a lot to be desired. I am looking for a diagram myself as a pack rat chewed off both ends of one vacumn hose and I cannot find where it attaches on the firewall.
