Gasoline Direct Injection Pump

Aftermarket gasoline direct injection pump product image by Spectra Premium

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.

Spectra Premium’s Gasoline Direct Injection Pumps provide reliable operating pressures for stable fuel combustion at low and high speeds, contributing to an efficient engine operation

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 a leading aftermarket coverage of the high pressure fuel injection pumps, although the technology might bear another name depending on the original manufacturer:

Part Components

Detailed components of the GDI pump: damper, pressure relief valve, oulet and inlet valves, cylinder, plunder and solenoid control valve

Accessories available

  • Gasket and / or O-ring
  • High pressure fuel line
  • Cam follower

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.

Replacement importance

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.
