This is the factory-listed Royal Enfield 148123/E – HOSE, FUEL, RETURN. Both the Interceptor 650 Euro 4 fuel-tank diagram and the Continental GT 650 Euro 4 fuel-tank diagram show this exact part number as the return-line hose, so we can safely list it for Interceptor 650 and Continental GT 650 only. 

It’s the moulded/formed hose that carries low-pressure return fuel from the injection circuit back to the tank. Because it’s OEM, the internal diameter, the factory bends and the length are made for the 650 frame and tank area – so it clears the frame spine, doesn’t kink, and seals correctly on the tank stub and the return connector. Generic fuel pipe often sits too close to the engine or pulls on the fitting; this one goes straight on. Fit this any time the old hose is cracked, hardened by fuel, cut during tank removal, or you’re restoring a bike that had its fuel lines modified.

FAQs

Q1. What does this hose actually do?
It’s the fuel return line – it routes excess fuel back to the tank in the 650 FI system. Using the correct hose keeps pressure stable.

Q2. My Interceptor 650 hose says 148123/E – is this the same?
Yes, this listing is exactly for 148123/E as shown on the official parts diagram. 

Q3. Can I replace it with generic fuel pipe?
You can in an emergency, but generic pipe may kink or sit wrong; this OEM hose has the exact bends for the 650 frame.

Q4. Will it fit my Continental GT 650 BS6?
Euro-4/BS4 GT 650 is confirmed. BS6 models use the same tank layout in dealer diagrams, but if your EPC shows a newer suffix, ship that

Q5. Do I need clamps?
Yes – reuse the OE 12.5–15.7 clamps or add 148344/A from the same page.
