Find the right Discovery 2 fuel and air route
Discovery 2 fuel and air parts split into two main routes: TD5 fuel system work and air filtration or intake work. Fuel parts cover pumps, filter housings, pressure regulators, pipes, seals and small fittings, while air parts cover standard filters, performance filters, MAF sensors and related intake routes.
| Job / route | Best place to start | Check before ordering |
|---|---|---|
| TD5 fuel system repairs | Discovery 2 Fuel System | Check part number, TD5 fitment, pipe route, regulator type and whether the part is shared with Defender TD5. |
| Air filter and intake service | Discovery 2 Air Filtration | Check standard or performance filter type, airbox fitment, MAF sensor position and any TD5-specific notes. |
| Fuel pump and tank fittings | Fuel pump and sender units, tank seals, retaining rings and locking rings | Check Discovery 2 TD5 fitment, pump brand, seal reference and retaining ring details before ordering. |
| Fuel pressure regulator work | Early 1-pipe and late 2-pipe fuel pressure regulators, gaskets, O-rings, strainer and rebuild parts | Check whether the vehicle uses the early 1-pipe or late 2-pipe regulator before ordering regulator parts. |
| Fuel filter housing and pipework | Fuel filter housing kits, air bleed valves, restrictor valves, non-return valve kits, fuel pipe sets and high-pressure pipes | Check filter housing type, pipe colour, tank-to-filter route, included fittings and original part number. |
| Fuel cooler and sealing work | Fuel cooler assemblies, fuel cooler O-ring kits, sealing washers and related coolant-side parts | Check whether the repair sits in the fuel, cooling or engine route and match the cooler or seal to the product notes. |
| Fuel and air testing | Fuel pressure test kits, water-in-fuel sensors, MAF sensors and related TD5 sensor routes | Check sensor function, connector position, test kit contents and whether the job belongs in fuel, air, electrical or engine sensors. |
Check Discovery 2 fuel and air fitment before ordering
Discovery 2 fuel and air parts need checking by engine, system route and component position. Many TD5 fuel parts are shared with Defender TD5, but Discovery 2-specific pipework, pump listings and sensor routes still need checking against the product title and fitment notes.
TD5 fitment
The live fuel range is mainly TD5-focused. Check that the product is listed for Discovery 2 TD5 before ordering fuel pump, regulator, pipe or filter housing parts.
