Protect your fuel system

Advanced High Efficiency Fuel Water Separator Diesel fuel acts as a lubricant in unit injectors. The film strength of diesel fuel prevents metal-to-metal contact between the plunger and barrel. Water can compromise film strength, resulting in scuffing and eventual seizure. Cat Fuel Water Separators have greater water removal capabilities essential for better protection of unit injectors. Fuel Water Separators also deliver longer secondary fuel filter life. · Removemorethan98%ofdebris10micronsandlarger · Virtuallyeliminatefreewaterinfuel · Remove87%ofdissolvedwater PrimeTime Priming Pump Cat PrimeTime Priming Pumps are easily installed on the frame or engine as retrofits.

Cat Fuel Water Separators are much more efficient than those produced by other manufacturers. This efficiency minimizes barrel-to-plunger scuffing and significantly reduces the chance of fuel injector failure.
