Fuel Pumps

[Leeman]

Im looking at buying a bosch o44 fuel pump for an upgrade, i've heard they are noisy, how noisy are they? Does anyone else use them? Would it be a good upgrade for the 34??

[Import S13]

they're not the quiestest of fuel pumps but they do a decent job and the sound isnt that bad its just a buzzing sound.

ive got a walbro 500hp one in mine and its a hell of alot quieter then my friends 044 plus mine has that little white sock thingo on it to help out.

G'day Lee

I just had an 040 put in and its fairly loud like pssshhhhhhhhh only before starting the car other than that I never hear it

In my experience the 040 is louder than the 044. The 044 is quiet most of the times.. some real hot days it buzzes away but the 040 was just "warbling" away no matter what the conditions..

thanx heaps guys, can you hear it while your idling Matt?

Has anyone upgraded their fuel pump on their 34??

I got it from www.nengun.com

Just checked the prices, one for your 34 is $331.30 delivered atm (good exchange rate)

High Flow Nismo Upgrade fuel Pump. 4.6 L/min( at P=294kPa,3.0kg/cm2), an increase of 125% compared to the standard pump.

I chose it because it's a straight swap for the stock pump, I think with the Bosch and Walbro's you have to modify the cradle it sits in?

modify the cradle yes, but it takes 15 min, and it flows a hell of a lot more..

what sort of dollars are you going to spend on the chase of kw's

what sort of dollars are you going to spend on the chase of kw's

I'll always be spending (its a skyline)! Looking at 250 kw at next upgrade, later down the track would like max of 300 kw.

then stick with the 044, get a aftermarket sock/filter from sprints of a 5ltr efi falcon, and rubber mount the 044 onto the stock cradle.

once installed you will never have to worry about fuel again until you go past 400 kws at the rears..

and it will sound the same as your stock pump.

I had an 040 in my S15 and it was noisy as a mofo - so much so I had it removed and put in a Walbro instead .... the 044 is even louder - a constant buzz - especially when the weather is warm, hence the fuel pump works harder for some reason.

I am fitting a Walbro 255lph and Malpassi fuel regulator in the next month or so - I have had them sitting in my garage for months ....

[Cubes]

If mounted correctly the 044 is no louder than the usual V8 commodore pump. Rubber mounting and correct positioning of the sock is the key.

Walbro FP here........... Shaun fitted it last time the car was tuned by him, and no dramas at all, can't even hear the damn thing!

[Pauly33GTS-t]

Mine sounds like.... like when you activate the front washers. that slight buzzing sound. i need to mount mine deeper tho to fix. i got 1/4 tank issue.

[Tangles]

Got a 040 sitting right at the bottom of the fuel tank in the Stagea. Mod'd cradle etc to make it fit right down low, also got a direct wire feed from the battery. Very loud, like a commy I guess, but hey who gives a f#, with a Stagea and the seraphic glass windows and some *beats* you cant hear a horn let alone a pump, lol

Has anyone upgraded their fuel pump on their 34??

Nope but my exhaust is pretty loud

Steve at AMMAR did mine he built the brackets and mounts, did a quality job, you can listen to it next cruise
