Your engine is Cummins isn’t it?
I would think you would have better luck going directly to Cummins because the way you are trying to get the OEM part going through F/L is costing you more as F/L will mark up the price to pay for their time.
Try going directly to Cummins because they can overnight any part from wherever it may be stocked. OTR truckers hardly ever have to wait weeks for parts like this.
We go directly to the components manufacturer, no matter what the brand name of the truck.
