A petrol tank is one of the few motorcycle parts where a wrong choice is immediately obvious – it either bolts on and seals, or it does not. This guide explains how to pick a replacement fuel tank for an Indian motorcycle so you buy once and fit it right.
1. Match the tank to the exact model and year
Fuel tanks change shape, mounting points, and filler position between model generations even when the badge stays the same. “Splendor” alone is not enough – a Super Splendor tank differs from a Splendor Plus or a Splendor Pro. Always buy against your bike full model name and, where possible, its model year or BS version. On autoss.in every tank listing names the fitment (for example, Royal Enfield Classic 350 BS4, Apr 2017 to Mar 2020).
2. Understand what you are buying: steel, capacity, and finish
Most factory replacement tanks are stamped from cold-rolled (CRC) steel and seam-welded, then powder-coated or painted. Capacity matters: a standard commuter tank holds roughly 10 to 13 litres, while models like the Royal Enfield Classic run larger. If your bike is fuel-injected, confirm the tank has the correct opening or provision for the fuel pump and level sender – a carburettor-era tank usually does not.
3. Check the fuel tap (petcock) and sender provision
The petcock mounts to a threaded boss on the tank. Thread pitch and position vary by brand. If your bike uses a fuel level sender, the tank must have the matching sender flange and hole pattern. Listing photos and the fitment table on the product page tell you whether it is a plain tank or one drilled for a sender.
4. Mounting brackets and rubber dampers
Tanks sit on rubber dampers and bolt through fixed brackets. Aftermarket tanks are usually supplied bare, so reuse your original dampers, bolts, and spacer rubbers. If a tank bracket spacing is even a few millimetres out, it will stress the frame mounts – check before painting or installing.
5. Paint, decals, and colour matching
Replacement tanks often arrive primed or in a base colour. To match your bike original shade you will need the factory colour code; a reputable two-wheeler paint shop can mix it. Matte and metallic finishes are harder to match, so factor that into the budget.
6. Pre-installation checks that save a return
Before fitting, inspect for transit dents, verify the filler cap threads, confirm the petcock screws in smoothly, and pressure-check the seams if you can. Fit with fresh fuel line and a new petcock gasket to avoid the most common leak point.
Bottom line
Buy by exact model, mind the fuel system type (carb vs EFI), and reuse your original dampers and hardware. Get those three right and a replacement tank is a straightforward, one-time job.

Quick Mechanic Diagnostic Checklist
- Confirm the full model name and model year, not just the brand
- Check whether your bike is carburettor or fuel-injected
- Verify the petcock thread and position match your original
- Confirm the tank has a fuel-level sender opening if your bike uses one
- Inspect for transit dents, cracked seams, or damaged filler threads
- Reuse original rubber dampers and mounting bolts
- Fit a new petcock gasket and fuel line at installation
Frequently Asked Questions
How do I know which petrol tank fits my bike?
Match the tank to your bike complete model name and model year (or BS version). Two bikes with the same badge can use different tanks, so use the listing stated fitment and message us with your bike details if unsure.
Are these petrol tanks genuine OEM or aftermarket?
They are OEM-spec replacement tanks built to the original dimensions and mounting pattern. We list the fitment and material so you can choose with confidence.
Can I repaint a replacement petrol tank to match my bike?
Yes. Most tanks arrive primed or in a base coat. Use your bike factory colour code for an accurate match, ideally through a two-wheeler paint specialist.
Do I need a new fuel cap and gasket?
Not always, but a new filler cap gasket is cheap insurance against leaks. If your original cap fits and seals, you can reuse it.
Will a tank for another model fit my bike?
Only if the mounting brackets, petcock position, and filler location match. Never assume cross-model fitment; check the bracket spacing and fuel system type first.
