Fuel Pump

[R32Abuser]

I have had teh following problems. Firstly the pump iis a Bosch 040 in tank.

Got the pump all fitted in by my mechanic and it was all sweet for a while.

I was turning around in a fairly cambered street and came to a halt to park wen all of a sudden i hear a (to the best of my descriptions) "buzzing" or "spitting" sound coming from the fuel pump. Later that day i took the pump out checked it all out caus i thought mayb it had (the hoseclamp holding it to the cradle) fallen and was vibrating against something. There was nothing wrong, the hoseclamp was fine and everything looked how it went in wen the mechanic put it in. Took it for a drive and went fine, doesnt do it when driving in a straight line, just when i come to a stop on a hill or a cambered road. My mechanic rekns it is a vacuum leak...Anyone had any similar experiences??

well ive had it probs like 1/3-1/2 full and it still does it, feels like it moakes no difference how full the tank is. Any ideas on possibly what it could be?

hahahah lol.

i had the EXACT FREEKIN PROBLEM.

it was ok then it would start making this bouncing noise. and the fuel presure was bouncing up and down.

they dont like the hi/low fuel pump voltage.

the first thing you need to do is to piss the fuel pump controller off.

(find the earths for the pump and ground them directly to the body)

also run a direct power line from the relay to the pump aswell.

located behind the boot latch area.

if that doesnt work throw it in the bin and get an 044.

bloody 040 pumps. (there only about 10% bigger in flow over a gtr one )

@ 3 bar. 040= 3.2litres/min

@3 bar gtr32=3.0 litres/min

(aproximate values with batery voltage(car ideling)

My Bosch makes a whole lot of noise too! When ever i have 1/3 of a tank or less it starts making all this weird noises and vibrates..lol
