Does the fuel filter get hot while running

Hi welcome main problems are the abs valves causing the 3 dash lights (search 3 amigos online) a really badly sited compressor can cause air suspension models to fail giving the bags a slow leak the V8 is a solid engine but can have radiator expansion tank and cap failures
the other issue is electrics windows and door looms are problematic

Options:

1) Fuel pumps can often go out "slowly" meaning sometimes they work and sometimes they don't. Eventually it will die and you will be no fuel to your engine.

2) It might be your fuel filter.

3) If you are getting fuel to the engine, it could be your spark plugs, plug wires, etc...

The ignition system is controlled by the ECM. Check power at fuse box in on right side under dash. Check fuses right side engine compartmentlower dash panel if all OK check power to ECM located right side "A" pillar in alloy box. this unit could be faulty if no spark at coils, assuming they have been connected correctly. may have to get tested for codes at L/R dealer or someone with test tool. Another source of problem may well be flat battery in transponder key. The indicator light on the dash willflash rapidly for 10 seconds if the vehicle has been unlocked with the remote and the drivers door is opened if the battery in remote is getting low

The fuel pump, like all vehicles these days, is located inside the fuel tank. To replace most of them, you have to drain and remove the fuel tank. Luckily for you, yours can be accessed from the top by removing the carpet etc. from the rear cargo area.

check so see if water runs out the tail pipe! if so head gasket

If your vehicle is a Discovery Series II, it is not equipped with a fuel filter. If it is a Discovery Series I it is in the right rear wheel well towards the front. Hope this helps out.

Best of Luck

for Land Rover Discovery 1999-2004 no more external Fuel Filter serviceable anymore...it's a built-in part with the fuel pump. so if you want to change the filter then change the whole fuel PUMP.

If you're standing looking at the rear of the vehicle, it's on the chassis rail on the right hand side rear wheel arch.

near the fuel pump. Listen for it. It is down low. In back, by the fuel tank.

I'm pretty sure that sounds like a thermostat problem. If you live in a hot climate expecially. Sister's Range Rover having the same problem in Florida.
