Customer Question:

My vehicle comes equipped with the fuel pump and sending unit as one unit.  Can I just buy the pump?


1A Auto Replies:

While many older vehicles had separate fuel pumps and sending units, most newer cars have everything assembled as one unit. Since these units are not meant to have individual parts serviced, they do require that everything is replaced as one unit.


Customer Question:

What are HIDs? Do I have them?


1A Auto Replies:

HID stands for High Intensity Discharge.


Customer Question:

When they scanned my car, the error code said it was “Bank ‘X’, Sensor ‘Y’”. What does this mean?


1A Auto Replies:

In order to read and diagnose oxygen sensors correctly, the computer gives each a sensor a specific name based on its bank and sensor numbers. 


Customer Question:

What is the difference between composite and sealed beam headlights?


1A Auto Replies:

Sealed beam headlights are a single unit that incorporates the lens, reflector and the bulb.
