Frequently Asked Questions

Which Exergy injector or pump fits my diesel truck?
Match the verified year, make, and model, then confirm the engine family, production split, fuel-system generation, performance level, calibration requirements, and exact Exergy part number.

Do Exergy performance fuel-system parts require tuning?
Modified-flow injectors and stroker or race pumps commonly require matching calibration and supporting fuel-system changes. Follow the requirements for the exact part number and the vehicle's current build.

What should be checked before installing a diesel fuel-system part?
Inspect for contamination, inadequate low-pressure supply, damaged lines, rail-pressure faults, and related injector or pump failures. Correct the root cause and keep every open high-pressure connection clean and capped.
