ALSO Lodged in M47R Diesel Power Derivatives
I am starting to prepare my 1999 CDI for its MOT. While checking at the rear of the offside sill area I found a small loose rubber hose which appeared to have come away from a small round unit fixed to outside of the rear footwell. It is located only a few inches from the inner sill face and just forward of the offside lower main suspension arm. It is rusted beyond belief, although the input and output tubes and the electrical connection is intact. There does appear to be traces of fuel in the pipes. It is now U/S.
What is its function ? Is it still required or can the tubes be bridged ? It will have to be replaced if it is a fuctional item.
On checking the Rover info CD I eventually located a part that appears to fit its description. It is labelled as SENSOR - HEATED OXYGEN - RHD (HO2S) on page CO908

Anybody got any ideas or Info ?? I would appreciate some assistance

Thanks Jupiter ( Drummond )

It sounds like the fuel pump for the fuel burning heater (FBH (Fuel burning heater.)).

Thanks Duncan, I had not thought of that. That will allow me to do a few tests.

Cheers Drummond

Well Duncan, it appears you are correct. I got a number off it ( eventually) and it says " Thomas Magnette 89372A diesel pump for fuel heaters. So now to try and get one. Thanks for your advice,

New ones on E Bay Drummond but not cheap plus you may need a new bracket, used ones also appear from time to time

Planning is an unnatural process, much better to just get on with things, that way failure comes as a complete surprise instead of being preceeded by a period of worry and doubt

Thanks Rob, Got one at our local scrap yard for £2.00 and it seems to work. Once cleaned up and painted it looks the part and fitted. Got other issues with TC warning light which I cannot get to go out. Will read your posts again and maybe come back on this.
Thanks again, Drummond
