Fuel Pump Nose

[Savin]

Story is started the car and let the fuel pump prime....then drove off...After 10 mins of driving the pump would eventually get a loud hizzing sound...

While revving the hizzing is loud but toleratable

but when i take my foot off the accelerate pedal to slow down or came to a complete stop, the hizzing sound would get really loud....

My fuel tank level is half way and i put bp ultimate...

Any one got any ideas?

PS. When a mate installed the fuel ppump it was running fine..Test drive it for 2 days then i stored the car for 6 months in the garage...6 months later started to use it today and all this happened.....

are these aftermarket pumps meant to be loud???

Hey man, i had a real noisy buzzy fuel pump wen i bought my car ,heard it from the moment i put ignition on, got louder wen i accelerated, i thought it was aftermarket until i took it out to change it. does ur car take a while to crank?

my old one died on me, turned out to be a shitty stock one,,maybe u should check the wiring on it, but otherwise from wat ive heard, aftermarket ones are meant to be a bit loud..

but yeh, the one i installed in my car only buzzes wen i turn ignition on, and never again

If its working, if you get it checked and its fine, no problem...........the noise, live with it, you could buy a dozen fuel pumps and they could all be just as noisy, some aren't but most are.

What pump did he install? Some aftermarket ones are rather loud, i have a Bosch 040 in my R33, and it is rather loud but i live with it.

Benzimo - my car cranks fine..i just gotta wait for the priming to finish which only takes 5 secs

I can live with the noise but i just wanna know if the fuel pumps are meant to have a loud buzzing sound when accelerating and on idle...

Aberax - Its a bosch 023 (big bro of 040 i think)

I think its alright man, bigger pumps will make noise, just live with it, but if it aint broke, dont fix it

My Walbro makes a similar noise, kind of like that noise your speakers make when they are not hooked up properly. Got really worried because I thought the Walbros were rather quite. Went to my tuner and all good just noisy, you get used to it.

Just turn the radio up louder to drown it out...hehe
