Different Fuel Filter Available To Prevent Premature Wear On Fuel Injection Pump Plungers And Barrels{1261,1251}

Usage:

Caterpillar Machines Powered By 3204, 3304, And 3306 Machine Engines

Some engine operating environments and/or fuel handling practices have resulted in premature wear on the fuel injection pump plunger and barrel. This can cause hard starting, dying at low idle, and low power symptoms. Field tests indicate the 1R-0750 Fuel Filter is effective in preventing premature wear on the fuel injection pump and barrel. The 1R-0750 Fuel Filter can be used in place of the 1R-0740 Fuel Filter where improved filtration is needed. The 1R-0750 Fuel Filter is approximately the same size and has the same capacity as the 1R-0740 Fuel Filter. The 1R-0750 Fuel Filter is recommended for use on machines where premature wear of fuel injection pump plungers and barrels is a problem.
