IMPORTANT: Starting in mid 2020 with the I-Series Trucks, Izuzu introduced an updated belt-driven vacuum pump design. The new pump has a longer snout and shaft than the previous design allowing for more robust bearing support of the shaft and greater durability. This Isuzu NPR vacuum pump can be retrofitted to trucks back to 2008 but will require use of a deep offset / dish type pulley. Note that some upfitted trucks have an additional belt in front of the main factory serpentine belt to run other accessories such as hydraulic pumps. In these applications this new style vacuum pump will usually not work because the longer shaft physically interferes with the extra drive belt.
If you have a pre-2020.5 truck and wish to retain the original vacuum pump setup and use your original flat pulley, see our related items below.
This pump is NOT the same as the original pump for the 6.6L application (Part numbers 97656980 / 8-97656-980-0). As of the time of this writing, the 6.6L pump is on international backorder, with none available anywhere. This Isuzu NPR Vacuum Pump will work in place of the original pump. It is totally identical to the original except for the location of the breather / fresh air line. Installing this pump on a 6.6L will cause the breather line connector to be very close to the engine, but it is workable and will allow you to get your truck up and running!
