fuel level sender, this replacement monitors fuel in the tank and provides the signal used by the dashboard gauge.

What This Product Does
The sender supplies fuel-level information to the instrument display. Its role is measurement rather than pumping fuel or regulating delivery to the engine. An unreliable indication therefore needs separate diagnosis from a starting or running fault.
Functions
- Monitors the quantity of fuel remaining in the tank.
- Provides an electrical input for the dashboard fuel indicator.
- Supports fuel monitoring between refuelling stops.
Technical Details
- Component: fuel tank level sender.
- Supplied references: 477919051B and 477919051C.
Symptoms of Fault
- Fuel indication remains at empty or full.
- The needle moves abruptly when travelling over uneven surfaces.
- The displayed level fails to increase after filling the tank.
- Readings vary intermittently or change with temperature.
- The low-fuel warning does not correspond with the fuel remaining.
- Corroded terminals or damaged sender wiring are visible.
Why Replacement Matters
Renewing a confirmed faulty sender can restore useful fuel-level information when worn contacts, internal deterioration or contamination affect measurement. Check the gauge, wiring, connectors and earth connections first, since these can produce similar symptoms. Inspect the sender seal during the repair; fuel odour around its mounting may indicate a sealing problem rather than an electrical fault.
FAQs
Does an inaccurate gauge always mean the sender has failed?
No. The instrument, its electrical connections and the vehicle wiring can also cause incorrect readings.
Will changing the sender resolve poor engine running?
Not usually. This component measures fuel level; delivery faults require their own checks.
Should the sealing ring also be renewed?
Renew an aged or damaged sender seal to address potential vapour leakage. Do not assume a seal is included with the sender.
