Reliable fuel delivery is critical for maintaining smooth engine performance, consistent power output, and proper combustion. Over time, the in-tank fuel pump can weaken, fuel level senders may fail or give inaccurate readings, and fuel filters can clog due to contamination.
This comprehensive kit includes:
1× OE Match Fuel Pump – OE ref no 99662010200
1× OE Match Fuel Tank Gauge (Level Sender) – OE ref no 99662080800
1× MAHLE Fuel Filter – OE Ref 99611025301
1× OE Match Gasket – OE ref PAB919133
Replacing these components together ensures optimal fuel system performance, improved reliability, and reduced risk of fuel starvation or pressure inconsistencies.
This kit restores the complete in-tank fuel delivery system by:
• Providing correct fuel pressure and flow
• Ensuring accurate fuel level readings
• Filtering contaminants before reaching injectors
• Preventing leaks through proper sealing
A properly functioning fuel system supports smooth idle, strong acceleration, and stable engine performance.
Worn fuel pumps and clogged filters can lead to hard starting, hesitation under acceleration, loss of power at higher RPM, and inaccurate fuel gauge readings. Inconsistent fuel delivery may also cause lean running conditions that affect performance and reliability. Replacing the pump, gauge, and filter together as a complete kit restores proper fuel pressure, protects injectors, and ensures smooth, dependable drivability.
Consider replacing this kit if you experience engine hesitation, intermittent stalling, hard starting, excessive fuel pump noise, or incorrect fuel level readings. It is also recommended as preventative maintenance on ageing 996 and 986 models.

The fuel pump relay is a precision replacement relay for the fuel-pump control circuit in the Porsche 986 Boxster and 996 911 (including Turbo and early Carrera GT) models. This relay controls the activation of the in-tank fuel pump, providing the necessary current to ensure correct fuel delivery under demand - making it vital for engine start-up, steady fuel pressure and safe operation.
Fits:
Porsche 986 Boxster 1997 - 2004
Porsche 996 C2 / C4 / C4S 1998 - 2005
Porsche 996 Turbo 2001 - 2005
Porsche 996 GT3
Porsche Carrera GT 2004 - 2006
* Please check and match the part number of your relay in your car before ordering.
• Position: Mounted in the front luggage compartment fuse/relay panel or subsystems - controls power feed to the fuel pump relay circuit.
• Function: When the ignition is turned on or engine is running, the signal from ECU or shift lever energises this relay, sending current to the fuel pump so fuel pressure builds before engine cranking - crucial for proper fuel system operation.
• Applications: Ideal when the original relay has failed, is intermittent, shows corrosion on contacts, causes fuel-pump drop-outs, engine stumbling, or fails the self-check.
The fuel pump relay is a critical yet often overlooked part of the fuel delivery system.
A failing relay may manifest as:
• Engine cranks but won’t start (fuel pump never powers)
• Fuel pump prime is silent when ignition is turned on
• Engine stalls at random after start due to loss of pump voltage
• Intermittent “no-fuel pressure” faults or ECU logged errors
Replacing the relay with a correct unit ensures the fuel pump receives the proper current, realises full system pressure, and avoids mis-diagnosis of fuel pump or ECU faults.
When to replace:
• Original relay is over 10 years old, exposed to heat or aftermarket modifications
• You’ve installed a new fuel pump but issue persists (relay may be the culprit)
• You’re diagnosing no-start or stall symptoms that point to fuel pressure drop-out
• You’re restoring or prepping your vehicle and want to replace all wear-prone electrical relays

OEMatch Fuel Pumps — Fit, Function, Confidence
A fuel pump supplies pressurised fuel from the tank to the engine, maintaining the pressure and flow your Porsche needs for reliable starting, smooth idling and predictable throttle response. OEMatch selects pumps suited to Porsche models, from restoration projects to routine replacement tasks.
Available Types
- In-tank electric pumps and modules
- External mechanical and electric pumps
- Pump modules with integrated sender units
- High-flow units for specific performance applications
Understanding OEMatch Fuel Pumps
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original fuel pumps.
OE (Original Equipment) refers to parts matching original specifications for the fuel pumps and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM fuel pumps engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
The pump moves fuel from the tank to the injectors at the pressure required by the engine management system. In many Porsche models the pump is mounted inside the tank as a sealed module, while other models use an external unit. Pumps depend on clean fuel and a stable electrical supply; some assemblies also include a sender or strainer. Choosing the correct type for the model and fuel system layout helps maintain consistent delivery and avoids premature wear.
Benefits Include
- Restores and maintains correct fuel pressure for stable combustion
- Improves starting reliability and throttle response
- Reduces risk of stalling and hesitation under load
Why Fuel Pumps Wear and Fail
- Contamination from dirt, rust or water in the tank
- Running low on fuel, causing overheating or cavitation
- Electrical faults such as intermittent power or corroded connections
- Clogged filters or blocked lines reducing flow and stressing the motor
The Importance of Replacing with OEMatch Fuel Pumps
Replacing a worn or failing pump restores the fuel pressure and flow the engine needs to run cleanly and responsively. Correct replacement helps prevent misfires, extended cranking and potential damage to injectors or fuel lines. OEMatch parts are chosen to suit Porsche systems and can support both routine maintenance and vehicle restoration efforts.
Advantages
- Direct-fit replacements engineered to match original dimensions and tolerances
- Corrosion-resistant materials and sealed assemblies for longer service life
- Options that match factory electrical and mounting interfaces for straightforward installation
Support & Advice
Fitting can appear straightforward but may require procedures such as correct torque settings and careful routing of hoses. If you lack the correct tools or model-specific knowledge, we recommend professional installation. Recheck fasteners and connections after initial running and observe for any diagnostic codes or fuel odours.
