Restore high-pressure fuel delivery to your direct-injection engine with the Standard Ignition Direct Injection High Pressure Fuel Pump GDP727. It drops in as a direct-fit replacement for the 2016-2023 INFINITI Q50 and 2017-2022 INFINITI Q60, taking over the job of the original mechanical high-pressure pump.
A direct-injection high-pressure pump is driven off an engine camshaft lobe and boosts fuel from the low-pressure feed up to the elevated pressures the direct injectors need to spray into the combustion chambers.
Common signs the original high-pressure pump may need replacing include long crank times, hard starts, a fuel-pressure related check engine light, or hesitation under load. If a failed high-pressure pump is the cause, this GDP727 replaces it; diagnose the fuel system first, since these symptoms can have other causes.

What vehicles does the GDP727 fit?
It is a direct-fit replacement for the 2016-2023 INFINITI Q50 and 2017-2022 INFINITI Q60. See the Buyer's Guide tab to confirm fitment for your vehicle.
What does a direct injection high pressure fuel pump do?
Driven by an engine camshaft lobe, it raises fuel from the low-pressure feed to the high pressures the direct injectors need to spray fuel into the combustion chambers.
What numbers does this pump interchange with?
It interchanges with PGD618, 2-34198, 166305CA0B, 166305CA1B, and 800-6332. The manufacturer part number is GDP727.
What are signs my high pressure fuel pump may be failing?
Long crank times, hard starts, a fuel-pressure related check engine light, or hesitation under load may indicate the pump. Diagnose the fuel system, since other parts can cause these signs.
Is this pump camshaft driven?
Yes. A direct-injection high-pressure pump operates off an engine camshaft lobe rather than an electric feed circuit.
