Buy Volkswagen Eos Direct Injection High Pressure Fuel Pumps

The HPFP sits on the end of the intake camshaft and boosts fuel from the in-tank pump's gentle 4-6 bar to as much as 200 bar (about 2,900 psi) before spraying it straight into the cylinders. (GoAPR) This ultra-high pressure lets the 2.0 T turbo engine make strong power while cutting fuel use and tail-pipe emissions. (Wikipedia) At idle the pump only needs around 40 bar (580 psi) to keep the rail happy. (NHTSA Static)

Inside, a small plunger rides a special cam lobe. Every rotation squeezes fuel in a tiny chamber, creating the high pressure needed for clean, fine mist at the injector tip. (GMB North America, Inc.) A sensor on the rail tells the engine computer how hard the pump must work; a control valve on the pump trims flow so pressure stays in the 50-350 bar window demanded by modern direct-injection systems.

• Low-pressure feed: 4-6 bar from the in-tank pump. (GoAPR)
• Idle rail target: 40 bar (580 psi). (NHTSA Static)
• Factory peak: ≈ 200 bar (2,900 psi) under load. (GoAPR)
• Diagnostic pass/fail: rail pressure must track spec within ±1 bar at idle according to VW TSB V201701. (NHTSA Static)

• Hard or long cranking starts.
• Sudden loss of power above 3,000 rpm.
• Check-engine light with codes P0087 (rail pressure too low) or P2294 (regulator fault). (FORVIA HELLA)
• Metallic ticking from the pump area.
• Gas-smell in oil (fuel dilution).

1. Cam-follower wear - the protective tappet can wear through, letting the pump piston scar the cam and destroy itself. (Steve's Imports)
2. Dirty or low-lubricity fuel - poor-quality gasoline can gall internal parts. (Hot Shot's Secret)
3. Skipped services - clogged fuel filter starves the pump; thin old oil hastens follower wear. (FORVIA HELLA)
4. Running the tank very low - overheats the in-tank feed pump, starving the HPFP. (Reddit)

• Inspect or replace the cam follower every 15-20 k mi. Many enthusiasts treat it like a spark-plug interval item. (Steve's Imports)
• Change fuel filters on schedule; use top-tier fuel to maintain lubricity. (FORVIA HELLA)
• Watch live rail pressure in blocks 106/140/141 with a scan tool; idle should hold ~40 bar. (NHTSA Static)
• Keep at least a quarter-tank of fuel to protect both pumps. (KEMSO)

All U.S.-market Eos models with the 2.0 T FSI (BPY) or early TSI (CCTA/CBFA) engines use this cam-driven HPFP. It shares architecture with pumps found on the same-year GTI, A3, Passat, and Tiguan engines, so part numbers such as 06F 127 025 K/L/M are common. (Always match VIN and engine code before ordering.) (NHTSA Static)

Replacing the pump is straightforward for a confident DIYer:

1. Relieve fuel pressure; remove the engine cover.
2. Unclip the electrical connector and banjo line.
3. Remove the three Torx bolts holding the pump to the housing.
4. Slide the old follower out; inspect for wear. Replace if scratched or cupped. (Steve's Imports)
5. Lube the new follower with engine oil, seat it, and install the new pump with fresh O-ring.
6. Torque bolts evenly (10 Nm), prime the system, and check for leaks.

Owners chasing big-turbo builds or E85 tunes swap to piston-enlarged pumps that raise flow about 37 % and safely push rail pressure past 240 bar while keeping stock ECU control. (BMP Tuning) Some kits quote up to 38.6 % more volume to feed 400+ hp setups on EA888 Gen-3 engines.

Direct-injection plus a healthy HPFP helps the Eos meet strict emissions by reducing unburned fuel and cutting CO₂ output. (Wikipedia) A failing pump can run the mixture lean, risking misfire and catalyst damage; prompt repair prevents both safety hazards and extra smog.

VW extended HPFP coverage on many 2009-2012 models (mainly TDIs) to 10 years/120 k mi-coverage is contingent on proven use of a mis-fueling guard. (NHTSA Static) Always check your VIN for open campaigns; some Eos vehicles have TSBs that guide dealers to test the pump before replacing it. (CarComplaints.com)

• VW technical bulletin V201701 outlines the 40 bar idle spec and guided fault-finding test. (NHTSA Static)
• HELLA TechWorld offers a step-by-step HPFP diagnosis guide with pressure ranges and fault trees. (FORVIA HELLA)
• CarComplaints tracks real-world owner reports-one Eos owner paid about $1,700 at 53 k mi after the fuel system failed. (CarComplaints)

Q: What does the HPFP actually do?
A: It turns low-pressure fuel from the tank into very high-pressure fuel (up to 200 bar) so the injectors can spray a fine mist straight into the engine's cylinders for more power and cleaner burning. (GoAPR)

Q: How long should the pump last?
A: Many pumps run 100 k mi or more, but follower wear, dirty fuel, or skipped services can shorten life dramatically. Regular checks keep it healthy. (Steve's Imports)

Q: Why is the cam follower so important?
A: The follower is a hardened "shoe" between the cam lobe and the pump piston. If it wears through, metal shavings ruin the pump and cam.

Q: My rail pressure is 25 bar at idle. Is that bad?
A: Yes-VW says the Eos needs ~40 bar at idle. Anything much lower points to a weak HPFP, clogged filter, or bad in-tank feed pump. (NHTSA Static)

Q: Can poor gasoline kill the pump?
A: Low-lubricity or contaminated fuel can accelerate internal wear and seize the piston. Using quality fuel and changing filters helps prevent this. (Hot Shot's Secret)

Q: Why does my car stall after hard acceleration?
A: Under heavy load the HPFP must keep pressure near 150-200 bar. A tired pump can't keep up, so pressure dips and the motor stumbles. (FORVIA HELLA)

Q: Are upgraded pumps street-legal?
A: Yes, as long as they keep factory fuel pressure control and do not alter emissions hardware. They simply supply more volume for tuned engines. (BMP Tuning)

Q: Does VW help with HPFP failures?
A: Certain years have an extended warranty-10 years/120 k mi-if a mis-fueling guard is installed and the failure meets VW's criteria. (NHTSA Static)

Q: Can I drive with a bad HPFP?
A: It's risky. Low pressure can over-lean the engine, melt pistons, and damage the catalytic converter. Tow or repair as soon as possible. (FORVIA HELLA)

Q: How do I spot early trouble?
A: Watch for long cranks, ticking sounds near the pump, fuel smell in oil, and rail pressure below 40 bar at idle with a scan tool.
