To the abyss of Land Rover Discovery lovers,

I would appreciate any kind of help before I drive this thing to the desert and blow her up!

So I received a P0090 error. Fuel pressure regulator 1, on my 2003 disco. I bought it (image attached) and now after searching for 3 freakin hours I have no F'n clue as to where the hell it goes! LOL, and I can't find anything online to give me the slightest hint.

Anyone know where it goes? Can anyone help me look like a real mechanic in front of the wifie, so I don't get that stare like "why did you buy it then?" look?

Any direction, clue, hint or laugh would be much obliged, thank you in advance.

 

I am fairly certain it’s on the fuel pump in the tank but I didn’t think it was replaceable. Maybe someone else here would know for sure.

 

I thought it was built into the pump, which is under rear carpet....

do you have a V8 or diesel?

 

D1 has a fuel regulator like that on the fuel rail.

 

Correct. That looks like a pre ael discovery fpr
