Royal Enfield 148549/C – Fuel Gauge Assembly for Continental GT 650 (Euro IV & BSVI, including 120th Edition) – Genuine OEM

Royal Enfield 148549/C is the genuine Fuel Gauge Assembly fitted in the fuel tank of the Continental GT 650. Official RE parts books for the Euro IV GT 650 list 148549/B – Fuel Gauge Assembly on the fuel tank page, with an O-ring and fixing screws. Later price lists and parts databases clearly mark 148549/A and 148549/B as superseded by 148549/C, all with the same description “FUEL GAUGE ASSEMBLY”.

The official RE spares portal now shows 148549/C – Fuel Gauge Assembly specifically for Continental GT 650 120th Edition – BSVI, confirming it as the current service part for modern GT 650 variants as well. Together, these sources make 148549/C the factory-correct replacement fuel gauge / in-tank sender for all Continental GT 650 generations, both Euro IV and BSVI.

Mounted in the tank, this unit measures fuel level and feeds the signal to the bike’s electronics, controlling the gauge / low fuel indication. Age, fuel contamination or tank work can cause the original sender to stick or misread, leading to random warnings or running out of fuel unexpectedly. Replacing it with a new 148549/C restores reliable readings with the exact float geometry, resistance values, connector and flange pattern specified by Royal Enfield.

To prevent returns, we do not list Interceptor 650 here – Interceptor uses a different fuel gauge assembly (e.g. 1030010/C for BSVI INT 650). Always confirm the part number in your VIN-specific microfiche before ordering.

Compatibility Table

*Years based on GT 650 production and Euro/BS transitions.

Not for Interceptor 650: fiche and RE spares assign a different part number (e.g. 1030010/C) to INT 650 BSVI, so we intentionally exclude Interceptor to avoid wrong fitment.

FAQs

Q1. Is 148549/C the same as the old 148549/B on my Euro IV GT 650?
Yes. The Euro IV partsbook lists 148549/B Fuel Gauge Assembly on the GT 650 fuel tank; dealer and price-list data show B is superseded by 148549/C, so 148549/C is the correct modern replacement.

Q2. Will this fit an Interceptor 650?
We do not recommend it. Interceptor 650 BSVI uses a different gauge assembly (e.g. 1030010/C on the RE portal), and mixing parts by “650 Twin” label alone leads to returns. For accuracy, always order the exact part number shown in your Interceptor’s fiche.

Q3. What symptoms indicate my fuel gauge assembly needs replacement?
Common signs: fuel gauge stuck on empty or full, low-fuel light not coming on (or always on), or readings that jump randomly even with a steady fuel level. After wiring and connector checks, the in-tank gauge assembly is usually the culprit.

Q4. Does this include the O-ring and bolts?
No. The GT 650 partsbook lists a separate O-ring for fuel gauge (e.g. 585456/A) and fixing screws. This listing is for 148549/C gauge assembly only; purchase the O-ring and hardware separately to ensure a leak-free install.

Q5. How can I double-check compatibility before buying?
Open your official Royal Enfield microfiche / RE Kart for your Continental GT 650, enter your VIN, and go to the fuel tank page. If you see 148549/A, 148549/B or 148549/C against “Fuel Gauge Assembly”, this part is correct for your bike.
