Where is fuel return valve?

[Gaurav]

Can anyone point that where is fuel return valve in 2000 Range Rover 4.6 engine (bmw one)? Is it near engine or integrated in or around fuel pump or somewhere in between the fuel line or fuel canister?

As upon shut off all fuel from rail goes back to tank and makes difficult to start again after 1 hr - 2 hr. Need to change that, provided i get the location of it. Searched in Rave and all its saying is fuel pressure regulator, and i don't know whether this FPR and valve is same or not.

Already changed new battery, new spark plugs, new HT wires, new CKPS and now finally figured out that this valve is culprit for cold start problem. Every time it makes me wait in ON position from 1 min - 5 min

Any help is appreciated. Cheers.

Thanks guys.

A little confusion here. You say BMW engine but these are Diesels on the 2000 model year RR. The petrol engines are Land Rover with Bosch injection from 2000 onwards. This is identified by what is commonly refered to as a bunch of bananas on the top as opposed to a squareish box with 4.6 on it. If you have the latter the pressure regulator is part of the fuel pump in the tank. There is a pressure reading valve (schraeder) on the right hand side(looking from front to back) at the back of the engine towards the top near to the bulkhead. I believe the pressure should be 3.5 BAR or 55psi approx.

Have you had the codes read ? I would be looking at tempreture sensors.

Sounds like the fuel pickup pipe in the tank.... how much fuel you got it in?

Its a petrol engine and with banana bunch on top, dont know why its called BMW engine, as few of my friends has been refering to as BM engine.

Secondly when i got CKPS it also says bosch at the bottom which came from landrover box.

Schrader valve in very inaccessible place tried using normal tyre gauge and unable to get hand over nipple.

No codes are appearing on the screen and no fault has been registered so far with the car comp system.

I doubt that, as its happening from three weeks and i got 2 full tank fuel top up so far.
