What This Pump Does
The 4954880 is a gear-driven fuel transfer pump. It pulls fuel from the tank through the suction line and feeds the filter head and injection system at working pressure. Gear drive means it turns whenever the engine turns, so output tracks engine speed. Thirteen teeth in the gear set, 3/4"-16 O-ring inlet and outlet ports, and the original mounting pattern so it bolts to the same face.
Failure is usually wear, not a sudden break. The gear set and housing wear, internal clearance opens up, and the pump loses volume at idle and cranking speed. The truck starts hard cold, stumbles under load, or the operator sees low fuel pressure on the gauge before the engine derates. On high-mile N14 and M11 engines this is normal wear rather than a defect.
Before you condemn the pump, rule out the cheap stuff. Restricted suction line, plugged primary filter, collapsed tank pickup, air leaking in at a fitting or a hardened O-ring. All of those look exactly like a weak transfer pump on a gauge. Pull a clean pressure and restriction reading on both sides of the filter head first.
Why These Numbers Cross
A gear pump crosses on four things: drive engagement, gear count, port thread and mounting pattern. This one is 13 teeth with 3/4"-16 O-ring ports on the original bolt pattern. Any number describing that same pump is the same part in the box, regardless of whose label is on it.
Cummins numbers 4010253, 3068889, 4010319 and 4010324 all land on this configuration through supersession and application-level part breaks. Cummins revises numbers when a supplier changes, a gear material changes, or an assembly gets rolled into a service kit. The pump body and the way it mounts stay the same, so the older number and the current number describe the same physical piece.
PAI 180123 is an aftermarket catalogue number for the same pump. It is listed here for identification only, so you can match a number stamped on a pump already in your parts room or on the unit that came off the truck. Listing it is not a claim of affiliation with, or endorsement by, any manufacturer.
Check Before You Order
Get the engine serial number off the dataplate or the block. N14, L10, M11, ISM and QSM11 all appear in this family, but part breaks inside those families are real and the serial number is what settles it. Cross-reference is a starting point, not a fitment promise.
Then read the old pump. Wipe the housing and find the cast or stamped number, count the teeth if the gear is exposed, and check the port thread with a thread gauge. If the number on your old unit is in the list above and the ports are 3/4"-16 O-ring, you are in the right place. If the number is not on that list, verify by VIN before you buy.
4954880 Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to 4954880. Use them to identify the part — then confirm the exact fit by VIN or the number stamped on your old unit before you order. An interchange is a starting point, not a fitment guarantee.

Frequently asked questions
Will this pump fit my N14 if the old one has a different number stamped on it?
Only if that number appears in the cross-reference list. Cummins revised this pump under several numbers, so 4010253, 3068889, 4010319 and 4010324 all describe the same gear pump. If your stamping is not on that list, confirm by engine serial number before ordering rather than assuming it crosses.
How do I know the transfer pump is bad and not the filter?
Take fuel pressure and inlet restriction readings with a gauge, before and after the filter head. High restriction ahead of the filter points at a plugged filter, collapsed pickup or a kinked suction line. Low pressure with normal restriction points at the pump. Do that test before you pull anything apart.
Is PAI 180123 the same part as 4954880?
It is the same gear pump configuration under a different catalogue number. We list it so you can identify a unit already sitting on your shelf or on the truck. The number belongs to that manufacturer and is used for identification only. Confirm by counting teeth and checking the 3/4"-16 port thread.
