Technical Bulletin APTB 06/11:
“Accurate information is vital to the Alliant Power warranty process. To better improve this process,
Alliant Power is requesting that the injector serial number be provided with all remanufactured G2.8 and G2.9
injector warranty claims. The injector serial number can be found etched into one of the spool valve coils.
This is the same location that the OEM part number is found.”
