With Expertise Built In , the OTR Remanufactured Fuel Injector is completely disassembled, cleaned, and thoroughly inspected in an ISO 9001 facility. Paramount to circumventing premature failure with the replacement parts, technicians determine how and why fuel injection parts have failed. Four things to consider in this process are fuel contamination, low fuel, precup issues, and clogged Diesel Exhaust Fluid Systems. Once the failure type is determined, all hard parts not strictly meeting OE specifications, including gaskets and seals, are replaced during assembly. Assembled units are then tested to ensure quality performance equal or greater than the original OEM specifications. As a hydraulic electronic fuel injector, each cylinders’ pump and injector is utilized to apply pressure in sending fuel to the engine. This heavy duty fuel injector guarantees providing your engine with the absolute amount of fuel and air bringing both power and performance to your engine for better cold starts and fuel efficiency.
