Description of Change: A new connector is used in the fuel injection lines groups used on the above engines and machines. The new connector has a 2.3 mm (.09") diameter orifice. The new connectors are installed in both the fuel inlet and outlet ports on each cylinder head. See the illustration. The new connectors help maintain a higher fuel pressure with less pressure fluctuations to the injector. The higher, more stable fuel pressure will help reduce cavitation.
