Frequently Asked Questions
Will Exergy 1-029-022 fit my Chevrolet Silverado 2500 HD?
It fits only the year range and engine application shown in the fitment table. Confirm the engine family, production split, fuel-system configuration, and exact Exergy part number before ordering.
What must match before this fuel-system component is installed?
Confirm the exact part number, pressure range, thread and sealing interface, connector or mating component, engine platform, and every manufacturer application note.
Should the fuel system be inspected before installation?
Yes. Diagnose contamination, low-pressure supply, rail-pressure faults, damaged lines, and related injector or pump issues first. Installing a new component without correcting the cause can damage the replacement part.
Installation Instructions
Follow the current Exergy instructions and vehicle service information for this exact part number. Work only on a clean, depressurized fuel system, cap open lines immediately, use new required seals, lubricate seals only as specified, and torque fittings and components to the published values. Prime and bleed the system correctly, check for leaks, verify commanded and actual rail pressure, and complete any required calibration before operation. Professional diesel-fuel-system installation is recommended.
