Product Overview
An APU fuel pump must deliver a steady low-pressure fuel supply so the small diesel can start and run consistently independent of the truck's main engine. Pump wear can cause extended cranking, intermittent APU shutdown, loss of prime or fuel starvation under load.
Matching replacement listings associate 41-7251 and 417251 with Thermo King TriPac, RV and RigMaster-style installations. Because auxiliary-power units can be retrofitted or serviced with different pump revisions, connector and fuel-port orientation should be compared to the removed pump.

Frequently Asked Questions
Can this cause an APU to shut off randomly?
A weak fuel pump can cause fuel starvation and shutdown, but controls, sensors and filters can produce similar symptoms.
Is 41-7251 the same reference as 417251?
Replacement listings commonly show both formats for this pump application.
Should I change the fuel filter too?
If the filter is due or contamination is present, servicing it at the same time is good practice.
