Known Defender (Classic) fuel system faults
Puma 2.4 EGR and injector return pipes
EGR valve carbon build-up and hardened, cracked injector leak-off pipes are pattern faults on the 2.4 TDCi and can mimic far more expensive fuel pump problems.
Parts commonly needed for the Defender (Classic)
On Td5 vehicles the injector loom, fuel pressure regulator and cylinder heads are common replacements, while Puma owners look for EGR valves, glow plug modules and injector leak-off pipes.

Defender (Classic) fuel system questions
What should I do if I put petrol in my diesel Land Rover?
Do not start the engine. If you have already driven, stop as soon as it is safe and switch off. Have the tank drained and the system flushed. Running a modern diesel on petrol can damage the high-pressure pump and injectors.
How do I bleed air out of my diesel fuel system?
Many modern Land Rovers bleed themselves when the ignition is cycled several times. Older engines may need manual priming. Follow the procedure for your engine, and fix the cause of the air leak.
