Fuel pressure sensor on Duratec

Anyone know where this is located? I cant find it on my CSR260 but the Stack Dash reckons it knows what the fuel pressure is!

Thanks.

The short answer is there isnt one. The Stack reading is completely spurious and should be ignored. Why Caterham didnt get Stack to zero out the reading as part of the changes they make I have never understood.

 

However the wiring is present and so the facility exists to add a fuel pressure sensor if you want to. It will require a threaded boss to be brased into the fuel rail though, unless you can find a coupling that allows it to be inserted between the fuel pipe and the rail.

 

Its a mod on my to-do list, but thats as far as its got.

Ah, no wonder I couldnt find it! I was interested because apparently if it existed it would be the same type of sensor as the oil pressure sensor. My oil pressure reading had suddenly gone to -99, so I was gonna swap the sensors to see if the oil sensor had broken, before spending £120 on a new one. In the end I had to risk it and buy one, luckily it turned out that it was indeed the sensor at fault.

Thanks for your reply.

Should you do decide to fit one, this should enable you to plumb it into the fuel system:

I've bought one but haven't bothered to fit it yet.

Worth having one I think, loss of fuel pressure can be serious! My Stack alarm get going off, and after I got a new fuel pump it turned out to be a dodgy regulator instead.
