entire tolerance stack up of fuel system tolerances (new and durability)
should be evaluated.
In some cases, limit flow hardware can be simulated by adjusting the
calibration tables to artificially simulate limit flow conditions. In other
cases, specific hardware can be built to represent limit flow, leak and
spray. This hardware should be selected in a manner to represent the
worst case minimum and maximum fuel delivery. This may include the
production and durability flow shift limits for the hardware. The hardware
evaluated should include the pump, regulator, and injectors. Additional
information can be obtained from your Delphi representative.
