I have a nismo one, there expensive but great quality no modding needed too fit in and does the job great, but comparing to other fuel pumps i can't say as ive never used any others

The bosch 040 is a intake pump

The bosch 044 is a bigger version than the 040 but is an external type pump

The bosch 023 is pretty much the same as the 044 but the intake style (ie it has a open base for the pickup on the pump)

Personally i would stay away from walbro and just get a bosch (i have fitted a 023 to my bros car and works a treat), if you want to spend more on a direct replacement then get something along the lines of a nismo pump.

A bosch 023 will well and truely get you your 350rwhp

NISMO!!!

[Birnie]

Tomei ! (see the DIY fuel pump thread)

Same item as Nismo, about $50 cheaper

[Jmaac]

walbro's are crap, bosch much better

[bumble_bee]

so the 023..is that internal??

sounds good..

but can i simply attach it to the cradle etc..

of do u gotta modify it heaps to make it fit??

so is the 023 a bigger fuel pump than the 044?

Bosch 023 = Nismo pump... unsure if it plugs straight into position, or needs modificaqtion to fit (doing my research atm lol)

023 Flows 168 L/hr @ 5 bar (internal) L=169mm D=60mm

040 Flows 102 L/hr @ 6.5 bar (internal) L=169mm D=60mm

044 Flows 200 L/hr @ 5 bar (external) L=196mm D=60mm

hey buddz..

if youre planning on pushing around the 350 mark then id suggest you go for the Bosch 023

[WRRR]

R34GTFOUR (see for sale thread) has a second hand 023 on R33 Bracket in Perth - buy? (edit)

If you're only after 350rwhp the simplest/cheapest would be a GTR pump (drop straight in).

or Antimatter (see for sale thread) had a second hand Tomei for sale that is the 276 l/hr drop in upgrade.

At 350 rwhp a 040 will be enough but needs a bit of fiddling about as does the 023 which will give you 276 l/hr (heaps)

$ vs stuff around.

Or go 044 with surge pot and pick up the advantages of a swirl pot and heaps of delivery but more $

The GTR pump is good but saying it is a drop straight in, is not quite right

THere's a bit of fiddling and choping and if you're not confident, you'll give up...or if you do get it in, you might get some noise from hitting the tank if you were a bit off.

But then, again, this applies to any of the Bosches too.

I'm not trying to paint a bad picture on the them, they're all good options but the only Drop In option is a Tomei or Nismo

Absolutely no fabrication needed whatsoever.

Evrything required is in the pack.

....and, apparently Walbros aren't up to the task, which gets mentioned quite alot and peeps still buy em cause they're cheap....

(i think their flow rates are true on a different amp/voltage of something...maybe 14volts? where the Nissan is 12volts?)

so with the tomei and nismo and gtr pumps..

are they a direct replacement of the stock pump..

lik can i just simply pull out the old stock cradle and drop the new one in...?

or do i got take the pump off and put the new one on..

but no modifications to cradle, lines etc.. is that correct???

unlike the 023 wer i have to modify..

i heard about changin the stock wiring too..is this also required wen fitting a new pump?

[Mr. Untouchable]

genuine Walbro pumps are fine.

genuine bosch pumps are fine

i have fitted a couple of walbro's and a 040, when they are wired right they are good.

you can pick up a 040 for $190ish off ebay, couple of 2.5" hose clamps holding it in the stock cradle and cut the earth after the plug on the tank lid cover and wire/earth it to the body and you'll be set.

that will be fine till the power bug returns then it will serve as a lift pump ready for a surge and 044 inline

[Mr. Untouchable]

ohh also i'd grab a new bit of fuel line, the rubber line that runs from the top of the pump the the metal line usually gets a bit old an tired after 10 - 15 odd years in the tank.

hey mate

i've just recently gone down this path.

i tried with an r32 GTR pump to put it into my r33 GTST...... lot of fiddling and i didnt get there (dunno if the r33 pumps are the same). I reckon if i had more time i could of got it to slide in.

Anyway i ended up buying the tomei fuel pump (comes complete with cradle thingy), this just comes straight out of the packet/box and slides straight into the factory guides. Tomei from what i hear is EXACTLY same as nismo.

Answer is: TOMEI/NISMO are direct replacement

Anything else requires fidling.....that's what i am able to put together (havent tried them all like all the bosch's....)

on the topic i've found that my tomei gives a slight hum in the cabin...its only very very slight....and i still like it. and then when you step on the peddle the hum steps up a pitch....kind of cool......but the sound is only just noticeable.

Thats another reason why i went tomei as with the other ones needing modifying you gotta be certain the pumps not lieing on the fuel tank wall -----> your "hum" becomes a "buz".

But price wise the tomei/nismo is a a bit more expensive than the others.....so comes down to your call.

[bumble_bee]

so do u get the upgraded wiring with the tomei pumps..lik do u got re-wire the new tomei pump..or do u get a harness that plugs straight-in??

so far that looks like the tomei pump is better pump to choose...

i heard of alot of people had to re-wire their car fuel pump wiring..well thats wat ive bein told by mates..

some reckon u dont have too..but yeah...coz of the voltage required by the new pump..some evan using relays..

is this required aswel???

(sorry if someone has already asked these questions)
