Larry,
You should be able to pick up a gauge at Auto Zone, Advance Auto, NAPA etc.
Vacuum gauges show when the engine is working in the most efficient manner. The driver can adjust the gear and throttle position to provide the optimum fuel economy by monitoring the engine vacuum.
Identify a vacuum line on your vehicle's engine. Vacuum lines are typically small, soft black rubber hoses. They are located on your vehicle's intake manifold. Once a vacuum line is identified, cut it in half with a razor blade knife and insert the plastic "T" from the gauge kit.
Install the vacuum gauge tubing. Insert tubing from gauge kit into the free end of the plastic tee that you have installed into the vehicle's vacuum line. Run this new tubing from the "T" fitting to the firewall of the vehicle making sure to route it away from moving parts and use zip ties to secure it. Run the new tubing through an access hole in your vehicle's firewall and into the interior of the vehicle.
Mount the gauge. Find a location where the new vacuum gauge will fit without interfering with any of the vehicle's equipment and is in the driver's sight. Place a strip of Velcro (hook and loop tape) on the flange of the gauge's mounting bracket and another strip onto the vehicle's dash. Insert the vacuum tubing into the rear of the gauge following the manufacturer's directions on the package. Once the tubing is attached, push the gauge against the Velcro on the dash.
Start the engine. Check the gauge for movement to ensure it's working. Remove the hood prop rod and close the hood.
A quick & fairly easy job,
Harold
