Bosch Fuel Pump Very Noisey

Hey everyone

About a week ago i ran my tank very low on fuel (3-4litres left), it would start turn over for a bit then die but eventually the tank/pump regained pressure and it started (has happened once before but car never started) . Didn't really notice until sunday that the pump (bosch 040) was whining even louder then normal. Doesn't seem to have effected performance (no pinging, surging or power drop) but the car doesnt build up much carbin, i never give it a boot full until the oil temp lifts off the stop 60-70deg then when i do a lot of built up carbin spews out the exhaust at the moment almost nothing comes out. When its just warming up in the morning it doesnt seem to produce as much fumes either.

Is the fuel pump on its way out? has anyone had something similar happen to them? should i just replace it to be safe?

Any help would be appreciated cheers

Was it blowing fuel clounds before?

As in ... has it always done it (cloud) but you've never taken notice of it? :)

Are you only noticing these things "as a result" of a bit of paranoia surrounding the low fuel perhaps?

If its a "new" thing, could be a fuel reg is failing, not uncommon and easy to check with a pressure gauge.

It has always blown fuel clouds but since ive noticed the fuel pump noise i havent seen it do it. Nar its not paranoia (i know the feeling though) my friend who has been in the car many times before asked about the loud whining noise too.

      Need AC Compressor for R32

      By R3N3 · Posted

      Haha im flattered! Although my poor boat is collecting dust in the garage, as it hasn’t been driven in like 6 months. I forgot the to put the trickle charger on too, so the battery is likely toast now.. I have the frenchys kit. It is fantastic. My only gripe was that the hard lines from the firewall needed some tweaking, however, this was mainly due to my specific turbo and dump combo. The weight and size packaging is much nicer too. I think I have some pics on my build thread somewhere.. my justification for the kit was more “why not” I had gone to the trouble to modernise just about every other part of the car..

      Does 98ron contain ethanol?

      By GTSBoy · Posted

      Actually, ethanol has probably never been cheaper, on a tax free basis, than petrol. With fuel excise being what it is, and only being levied on the hydocarbon component, not the ethanol component, and ethanol for non-drinking purposes not being subject to liquor excise - E85 was cheaper, but not because the combustible liquid itself was particularly cheaper.

      Will I Need A Retune After Cahanging My Catalytic Converter ?

      By Murray_Calavera · Posted

      Maybe? If changing the cat to a higher flowing cat, caused the turbo to spool more quickly, and those areas of the map had not been tuned for the boost level it is now seeing, then yes you would need a re-tune. How dangerous it is running without the updated tune would depend on how far out the tune is with the now higher boost levels, how the engine protection has been setup, is the ECU compensating with a wideband sensor, is the boost control closed loop blah blah million other things... But yeah having said that, I wouldn't be surprised if changing out the cat for a high flow, in say a full 3" exhaust, made no noticeable difference at all.

      Ah yep. I asked a auto electrician about getting a cheap rebuilt alternator vs a new one. He also said he used to it back in the day but it ended up costing similar to what a new one would and recommended getting a new one,.
