Review on Dorman 47076 Vacuum Amplifier: Ultimate Performance Enhancement Solution by Matthew Oumer

This vacuum canister allowed me to repair the HVAC system on a Ford E-350 van without any additional parts. I was able to disconnect the existing vacuum lines and fittings from the old, broken canister, route the line back through the firewall, and connect the lines to the canister. The original fittings of the vacuum lines are attached to the canister. I did not reinstall the original Ford check valve as it appears to be installed in the canister. It was easy and now everything works as usual.
