New Engine Pressure Group Available{0600,0770,0781}

Usage:

The new 6V9450 Engine Pressure Group is available. The new group is a replacement for the former 6V3150 Engine Pressure Group which is canceled. The components of the former 6V3150 Engine Pressure Group are still serviced. The new engine pressure group will make it easier to check engine performance. The following is a list of some of the advantages of the new 6V9450 Engine Pressure Group over the former group.

1. All of the gauges have both metric and U.S. scales. The metric portion of each gauge is shaded in yellow.

2. The former 2 1/2" compound gauges have been replaced by 4" compound gauges. This provides easier reading and better resolution.

3. Quick disconnect tube fittings are used. This makes tubing installation quicker and easier.

4. The former black tubing has been replaced with clear nylon tubing. This allows the user to see if anything is in the tubing before it is used.

5. The new carrying case provides more room for storage of accessories.

6. The new pressure conversion chart is included that provides conversions between kPa; psi; in Hg; mmHg; cmHg; in H₂O; Atm; BAR and kg/CM².
