GuestyR33 Posted January 26, 2006 Share Posted January 26, 2006 Hey everyone I wasn't sure where to post this, but since im from vic, i thought i'd ask someone from vic. lol. Im looking at buying an aftermarket fuel pump for my r33 gtst which needs to be able to handle a fair amount of power. I was recommended by autobarn to use a bosch 044. I don't know much about fuel pumps. i believe these are external? I've been told by friends that these can be quite noisy. Could someone explain wat that means. Also last night i was told that i would be better off getting a Walbro fuel pump. Are these internal or external? Wats the best thing for me to do. I didn't wanna spend more than probably $250. Just not sure the best option to go for. Any help would be very much appreciated. Cheers Guesty Link to comment https://www.sau.com.au/forums/topic/103369-fuel-pump-question/ Share on other sites More sharing options...
Downforce Posted January 26, 2006 Share Posted January 26, 2006 044 is external. unless you're intending to output over 350kw at the wheels i would stick with an internal bosch 040, which you can buy for under $250. Walbro's are shit dont bother. Link to comment https://www.sau.com.au/forums/topic/103369-fuel-pump-question/#findComment-1899825 Share on other sites More sharing options...

cerci Posted January 26, 2006 Share Posted January 26, 2006 actually...i brought a bosch 040 for my r33gtst, the workshop told me to get rid of it, hard 2 put in, surges around corners and to put in a walbro...said there much better...this was from a respected performance shop...havin already brought my pump i decided to go my own way and put the 040 in.....works fine, lil noisy Link to comment https://www.sau.com.au/forums/topic/103369-fuel-pump-question/#findComment-1899901 Share on other sites More sharing options...
R31Nismoid Posted January 26, 2006 Share Posted January 26, 2006 walbro's just dont flow what they are claimed (from what ive found) We went from AFR's in the 12's... To into the 10's by just swapping a Walbro with a Bosch So yeah, proof was in the pudding for me Link to comment https://www.sau.com.au/forums/topic/103369-fuel-pump-question/#findComment-1900073 Share on other sites More sharing options...
SXR Posted January 26, 2006 Share Posted January 26, 2006 Walbro's are good in respect to fitting and noise but definately not reliable....I have 2 cases which burnt out with in 6 months Bosch 040 is good and reliable, little harder to fit and probably wont sit far down in the tank...so if your low in fuel you might get surges Link to comment https://www.sau.com.au/forums/topic/103369-fuel-pump-question/#findComment-1900104 Share on other sites More sharing options...
Downforce Posted January 26, 2006 Share Posted January 26, 2006 any particular reason why you say walbro pumps are shit? <{POST_SNAPBACK}> unreliable, know of 2 people who've had a walbro "500hp" pump fail on them and they were supposedly genuine pumps. the walbro pump is physically smaller than the bosch 040. the bosch IS a prick to install, but remember that if you go for an external pump you will also need a lifter pump inside your tank regardless... certainly not a $250 excercise.

Sass Posted January 26, 2006 Share Posted January 26, 2006 (edited) the walbro's are rated at 15volts in the r33 they only run at 12volts so they never run at their optimum charge, hence "they're crap" run a 15volt direct circuit to them and they should be OK. skyline r33 gtr pump should be fine for your requirements and is a direct fit. the bosch is only noisy if installed incorrectly. normally it should be quiet Edited January 26, 2006 by sarahB Link to comment https://www.sau.com.au/forums/topic/103369-fuel-pump-question/#findComment-1900167 Share on other sites More sharing options...
Sass Posted January 26, 2006 Share Posted January 26, 2006 if you plan for like 300rwkw plus then 040 is fine, but there are lots of other things to be worried about for that power level than just the fuel pump Link to comment https://www.sau.com.au/forums/topic/103369-fuel-pump-question/#findComment-1900168 Share on other sites More sharing options...
R31Nismoid Posted January 26, 2006 Share Posted January 26, 2006 i wasnt running off the stock loom, was running direct voltage to the pump it was all done right, fear not.

kasanoff Posted January 26, 2006 Share Posted January 26, 2006 hey GuestyR33... i've got a Bosch 040 for sale if you're leaning in that direction - never got round to fitting it and i don't need it atm. here's the link to my post: http://www.skylinesaustralia.com/forums/in...opic=100789&hl= /end shameless plug Link to comment https://www.sau.com.au/forums/topic/103369-fuel-pump-question/#findComment-1900205 Share on other sites More sharing options...

Al Posted January 26, 2006 Share Posted January 26, 2006 I have a Bosch 044 external installed in the boot and it is pretty damn loud, but i have gotten accustomed to the sound :lol: Ever hear speaker noise from a stereo system with earthing issues or rca's running along side the power cables? Well the sound is similar to that but deeper and a little louder. Definately heard inside cabin, and over a loud exhaust. The Bosch 040 are alot quieter, and can only be generally heard while primming the engine b4 start-up.

R31Nismoid Posted January 26, 2006 Share Posted January 26, 2006 mines in my boot (external) and its not as loud as other peoples... guess its all mounted together under the surge tank to keep the noise down Link to comment https://www.sau.com.au/forums/topic/103369-fuel-pump-question/#findComment-1900818 Share on other sites More sharing options...

adznight Posted January 28, 2006 Share Posted January 28, 2006 I'm running around 200k/w at the wheels with the usuall mods and I'm using a Bosch 975, its' internal and not toooo loud. It's fine for 200-250 at least I considered an 044 but couldn't justify it plus it's a lot more expensive to setup.
