Keep your direct-injection V8 supplied with properly pressurized fuel using the Standard Ignition Direct Injection High Pressure Fuel Pump (GDP408). Driven off the engine, it draws low-pressure fuel from the tank-side supply and steps it up to the very high pressure the direct injectors need to spray fuel straight into the combustion chambers. It installs as a direct-fit replacement for the 2013-2016 Hyundai Equus, 2013-2014 Hyundai Genesis, and 2015 Kia K900 — all with the V8-5.0L engine.
Diagnose the underlying fault before replacing, and consult the vehicle service information for the correct installation procedure and torque specifications.
Interchange: Manufacturer part number GDP408.
What does this pump do?
It's a direct-injection high-pressure fuel pump. Driven by the engine, it takes low-pressure supply fuel and raises it to the high pressure the direct injectors need to spray fuel into the combustion chambers.
Which vehicles does the GDP408 fit?
It fits the 2013-2016 Hyundai Equus, 2013-2014 Hyundai Genesis, and 2015 Kia K900, all equipped with the V8-5.0L engine. Confirm fitment for your vehicle before ordering.
How many pumps do I need?
The listed V8-5.0L applications use two high-pressure fuel pumps per engine, so plan the quantity accordingly for a complete job.
What are signs the high-pressure fuel pump may be failing?
Long crank times, hard starts, hesitation or power loss under load, or a high-pressure fuel-system trouble code can indicate a failing pump. Diagnose the cause first, since other parts can produce similar symptoms.
Do I need any special steps to install it?
Yes. Consult the vehicle service information for the correct installation procedure, sequence, and torque specifications, and whether any fasteners or seals should be replaced.
