Hi Waybomb,
once again, nice 'talking to you'.....to put you in the pic. I bought this car some while ago without realising that the neeeeeeeeeeeee noise wasn't normal..it was only when I spoke to my brother (I.L.) that I realised it shouldn't do that.....them came the tests.......back off at speed (which I'm lead to believe, kills the fuel flow) and hey-presto....the sound dissapeared...returning when I re-commenced 'pedal'....every time....so it HAD to be the fuel pump whining...
If. as I suspect, something (poss filter) is making it whine, then I need to get it sorted before the added pressure on the pump makes it fail.The conclusive evidence was to tansfer the 'noisy' pump on to another car, as, above which proved it wasn't the pump itself where the fault lay. Think I'll have to try a specialist before the pump expires

Best Wishes....Tony
