This Fuel Relay is compatible with a range of Citroën and Peugeot models, providing a reliable solution for auto mechanics and DIY enthusiasts looking to repair their vehicles. Always verify fitment before purchasing to ensure compatibility with your vehicle’s specific model.

Product Description

This Bitron fuel relay (part number 240109) is a direct replacement designed for certain Citroën and Peugeot vehicles and is supplied with a short wiring pigtail to simplify installation. The relay controls power supply to the fuel pump, ensuring reliable pump operation during engine start and running conditions. Built for professional workshops and experienced DIYers, this unit is ideal when the original relay shows signs of failure such as intermittent pump operation or no fuel pump activation.

Key Benefits

• Direct fit replacement for compatible Citroën and Peugeot models.
• Supplied with a wiring piece for easier connection and quicker installation.
• Useful spare for fast troubleshooting in the workshop — often searched by part number 240109 or 19207L.

Technical Information

• Manufacturer: Bitron
• Model: Citroën, Peugeot (e.g., Peugeot 607)
• Product Codes: 240109
• Additional Numbers: 19207L

Installation Recommendations

1. Always disconnect the vehicle battery before starting work to avoid short circuits and to protect vehicle electronics.
2. Locate the relay in the vehicle’s fuse/relay box. On many Citroën/Peugeot models the fuel relay is found in the engine bay fusebox or interior fuse panel—consult the vehicle’s fusebox diagram for exact location.
3. Remove the old relay and unplug its connector. If fitted, detach any retaining clips or brackets carefully to avoid breaking plastic parts.
4. Connect the supplied wiring pigtail to the relay and to the original connector, ensuring secure and corrosion-free connections. Fit the new relay into the socket firmly.
5. Reconnect the battery and prime the fuel system (turn ignition to ON for a few seconds) to check that the fuel pump activates and there are no warning lights or fault codes.
6. After installation, start the engine and monitor for correct operation and any abnormal noises. Re-check connectors for tightness after a short test drive.

Why This Part Commonly Fails

Fuel relays are electromechanical components and can fail for several typical reasons: contact wear caused by repeated switching, overheating from high current draw of an aging fuel pump, corrosion or moisture ingress at connector terminals, and electrical spikes or poor grounding. Symptoms of relay failure include no fuel pump activation, intermittent engine starting issues, or the pump running only sporadically.

Notes for Mechanics and DIYers

This relay is frequently identified by its part numbers (240109, 19207L) when searching spare part catalogs. For efficient workshop workflow, keep spare relays and short wiring pigtails in stock for models known to use this unit. If vehicle symptoms point to fuel delivery faults, confirm pump current draw and check wiring and fuses in addition to replacing the relay to avoid repeated failures.
