conz1 Posted June 26, 2014 Share Posted June 26, 2014 Hey guys, just after some help my car has recently developed a high pitched whine when going above 1.5k. I've spoke to a few people and they have said it could be interference? I didn't know if anyone could shed some light on this for me. The sound can only be heard from inside of the car. Possible fuel pump issue maybe? Thanks in advanced Quote Link to post Share on other sites
Gainzy Posted June 26, 2014 Share Posted June 26, 2014 At first I thought wheel bearing but now I reckon it's a walbro fuel pump there meant to be noisy little buggers Quote Link to post Share on other sites
patman Posted June 26, 2014 Share Posted June 26, 2014 I got a walbro on mine yep they bloody whine alright, even noisier if you have stripped the back out 👍 Quote Link to post Share on other sites
conz1 Posted June 26, 2014 Author Share Posted June 26, 2014 It's the standard fuel pump as far as I'm aware lads I have a walbro pump in meaning to put in. It does it on idle as well, but same as before can only hear it inside Quote Link to post Share on other sites
daniel_g Posted June 26, 2014 Share Posted June 26, 2014 Not a lot else it can be, is your car got quite a few mods ? Chances are its got an uprated fuel pump, standard pumps are fairly quiet. Quote Link to post Share on other sites
Ollieh17 Posted June 26, 2014 Share Posted June 26, 2014 Is it your girlfriend in the passenger seat? Mine whines above 4,000rpm Quote Link to post Share on other sites

JayJ Posted June 27, 2014 Share Posted June 27, 2014 Same here, but it starts at 3000rpm no matter if you are on boost or vacuum. The sound also stops at 3000 if you are engine braking from the higher revs. I have to make an earthing kit first to make sure it's not interference as it sounds like it. It's also hard to say where it comes and I don't want to rev the car too much on our parking hall where sound echoes quite well. Timing belt kit, water pump and alternator has been changed recently, but I think it's not related to one of those even the sound started appearing lately. Quote Link to post Share on other sites
amatthews45 Posted June 27, 2014 Share Posted June 27, 2014 If you don't like noisy pumps then you should check out HRC's pumps! Longer warrenty and much quiter. The whine in question does sound like fuel pump best have a look. If not maybe a worn pulley in engine bay? Quote Link to post Share on other sites
conz1 Posted June 27, 2014 Author Share Posted June 27, 2014 The car did have a few mods on it when I first got it so maybe the pump is uprated. I'm going to him have a over look and see if it looks like someone has changed it or drive with the back seat up and see if it gets louder. It's just weird as it just started happening out of no where. Haha, Ollieh17 I think I whine more when she's driving it Thanks for all the help guys! I'll let you know if it sounds like the pump or not Quote Link to post Share on other sites
