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.....

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

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)

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

      Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

      Leak from Tokico BM50 Brake Master Cylinder

      The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/
