When the rail pressure falls off at the top of the run, the injection pump is out of capacity — no tune recovers that. The Exergy 17-24 Duramax L5P HP4 Pump (store SKU xrgE04 10702) restores the volume the Duramax L5P needs to hold pressure under load.
- HP4 platform — confirm which pump your truck left the factory with, since the families do not interchange.
- Tested through its full operating range before it ships, so it arrives as a known quantity rather than an unknown one you commission on the truck.
- Feeds rail pressure rather than replacing tuning — pair it with a calibration that expects the extra volume.
Fits: 2017-2024 Chevrolet Silverado 2500 HD/3500 HD and GMC Sierra 2500 HD/3500 HD with the 6.6L Duramax L5P.
Perfect for a build that has outgrown the factory pump and is losing rail pressure at the top end.
