The Engine Vacuum Pump 8972410351 is a critical component designed to generate consistent vacuum pressure for brake boosters and other vacuum-dependent systems in Isuzu NPR and NPR-HD trucks equipped with GM V8 gasoline engines. Vehicles with insufficient engine vacuum rely on this pump to ensure safe braking performance and proper operation of auxiliary systems.
Manufactured to OEM specifications, this vacuum pump delivers stable vacuum output across varying engine speeds and load conditions. It features a durable housing, precision internal components, and sealed construction to withstand heat, vibration, and long-term engine operation common in medium-duty commercial vehicles.
This unit is a direct replacement for Isuzu part number 8972410351, requiring no modifications for installation. It is compatible with a wide range of GM V8 engines, including L96, LQ4, and L31, used in Isuzu NPR / NPR-HD chassis from 1995 through 2019.
Ideal for brake system repairs, vacuum loss issues, or preventive maintenance, this vacuum pump helps restore factory braking feel, improves safety, and ensures reliable daily operation in delivery, utility, and fleet vehicles.
