Delphi HM10144 direct injection high pressure fuel pump for the 2016-2019 BMW 750i 4.4L and other vehicles is the mechanically driven pump that raises fuel to the high pressure a gasoline direct injection (GDi) system runs on.
- Delivers fuel at high pressures that can range from 2,000 to 2,800 PSI
- High-flow mechanical drive builds rail pressure quickly for fast start times
- Fuel goes straight into the engine combustion chamber, which is meant to increase horsepower and fuel economy
- Uses the latest generation of OE technology for GDi from Delphi, a Tier 1 supplier of GDi systems to global OEMs
- Meets OE specifications
Hard starting, a long crank or rough running can point to a weak pump, though other fuel-system faults produce similar symptoms. Before you replace the pump, rule out the low-pressure fuel supply and the wiring, and have a shop test fuel pressure instead of guessing.
This left-position pump also fits the 2016-2019 BMW 750i xDrive 4.4L and the 2017-2019 BMW Alpina B7 4.4L, and the 2016-2019 BMW 750i 4.4L takes one. If your BMW is not named here, look it up in the "Vehicles it fits" section, where the other vehicles are listed.

Frequently Asked Questions
Does the Delphi HM10144 fit the 2016-2019 BMW 750i xDrive 4.4L?
Yes. The Delphi HM10144 is listed for the 2016-2019 BMW 750i xDrive 4.4L, and each vehicle takes one pump.
What comes with the Delphi HM10144 fuel pump?
The Delphi HM10144 comes with the direct injection high pressure fuel pump and an instruction sheet.
What fuel pressure can this direct injection fuel pump deliver?
It can deliver fuel at high pressures ranging from 2,000 to 2,800 PSI. Its high-flow mechanical drive builds rail pressure quickly for fast start times.
Can a weak high pressure fuel pump make a GDi engine slow to start?
It can, because the mechanically driven pump builds the rail pressure the engine needs for a quick start. Rough running is another sign a weak pump can produce.
Does Delphi offer tech support for GDi fuel pumps?
Yes. Delphi runs a technician support hotline staffed by ASE certified technicians at 1-877-463-3574, and it also offers GDi-specific training classes.
