Gasoline Direct Injection Pump
The gasoline direct injection pump is located in the engine bay and supplies precise amounts of fuel directly to the combustion chamber, which reduces inefficiencies and increases power compared to indirect injection fuel pumps.
- Designed to OE fit, form and function
- Ease of installation due to OE style connector
- Designed to minimize negative impacts on the engine, improve fuel economy and reduce harmful emissions
- Extensive quality control at all levels of production
Industry Coverage
In 2017, 40% of new vehicles sales featured GDI Technology and GDI fuel pumps, for a projected 6.7 million new vehicles.
Analysts project that this proportion will increase: 49% of new vehicles in 2020 are expected to have a gasoline direct injection fuel pump.
Other Manufacturer Terms for GDI Pumps
Direct gasoline injection was first developed in the early 20th century for fighter planes until Mitsubishi introduced the first modern automotive GDI in 1996 . From a low 2.3 percent of new cars in 2008, the use of GDI pumps grew quickly to represent more than 40 percent of the current market.
Spectra Premium offers aftermarket coverage of the high pressure fuel injection pumps, although the technology might bear another name depending on the original manufacturer:

Common GDI Pump Failure Symptoms
- Lack of maintenance
- Wrong oil
- Pressure and temperature sensors
- Low pressure from failing solenoid
- Leaks
Failing to replace a damaged or malfunctioning high-pressure fuel pump may shorten the overall lifespan of the engine while reducing fuel economy. Additionally, since the injection timing will be off-key, rise in harmful emissions is to be expected which could lead to catalytic converter failure if not handled in time.
How it works
The high pressure fuel injection pump supplies high pressure fuel in Gasoline Direct Injection (GDI) systems. Mechanically-driven by the camshaft lobe, the pump delivers operating pressure from 30 to 250 bars or 100 to 2,900 PSI. More Details.
