Exergy E05 40105 Fuel System Saver Inlet Metering Valve FCA MPROP

The Exergy E05 40105 Fuel System Saver is an improved inlet metering valve (also known as FCA or MPROP) designed to provide affordable protection for high-pressure fuel system components against costly CP4.2 pump failures. Starting with a new Bosch inlet metering valve, Exergy replaces the factory single-layer screen with a significantly enhanced filtration system.

Advanced Filtration Technology:

• Dual-layer 10-micron stainless steel screen (over 8x finer than factory 85-micron screen)
• Stainless steel frame construction prevents failure when debris accumulates
• Will not tear or delaminate like factory plastic-framed screen
• Captures metal contaminants before they reach injectors and sensors

Performance Benefits:

• Increases injector survivability by more than 85% during CP4.2 pump failure events
• Loads up quicker than factory screen to shut down engine faster, minimizing damage
• Flow tested with no measurable performance loss, even with 10mm stroker CP4 pumps at 4500 RPM
• Proper deburring and clean assembly processes ensure fuel system cleanliness

This cost-effective insurance policy can potentially save thousands of dollars in fuel system repairs by preventing debris contamination throughout the high-pressure fuel system when a CP4.2 pump fails. Exergy recommends that if pump failure occurs with a System Saver installed, you may not need to replace injectors unless symptoms are present after pump replacement.
