Fuel pumps other than Walbro?

[Darius]

What is everybody running for a fuel pump? After reading up on fuel pump curves and such, I was looking to find an Apexi GT-R, Skyline, or Supra fuel pump. I have looked a little bit for these but can't find an online shop that carries the former two. Why do so many people run Walbro and not better, higher-flowing pumps?

[96EclipseGST]

300zx TT pumps are really good... a friend broke mine so i had to switch to my walbro 255.

[Carl H]

supra tt stock pump is rated at 290lph, which is more than enough fuel for most ppl as it runs out of steam at round 500hp...else get a tomei pump, i personaly run a r32 gtr tomei pump and it works a treat.dont bother with walboro imho.

I just installed my stock R33 rb25 fuel pump. And I was wondering what HP it supports?

not much more than a mildy modded rb25 can put out (on stock turbo that is).if you are chasing power better be prepared to step it up to something else...

How does the supra tt pump fit in the 240 tank? Does it use the same mounting hardware as the OEM pump or do you have to buy it with its own and modify it to fit the 240? My future power goals are about 400-450 but right now I just want to get the damn thing on the road. All I've done to it is install it and uninstall it like it was my job.

[DrifterTom]

you always use your mounting junk. you just take te pump off and replace it with the new one.

[Swedish Mike]

If you are looking for a new pump you got the Bosch 040, it can handle higher fuel pressure than Walbro and use fittings instead of hose, everything is better and bigger than Walbro.Can handle around 600 Swedish hp. Walbro around 450 hp.

my vote goes to the tomei pump. it comes assembled with a new sock and everything. you take the old fuel pump assembly out, drop the new one in, plug it in and go. Plus the tomei comes with a pressure regulator so you don't have to use an adjustable FPR to make things run right. SPL parts can hook you up SEX:

So what one of those pumps do I want for the S13 with an RB25DET?

[armysweitzer]

ditto for rb20.

[Bluefire]

Go with the supra TT fuel pump. You can get them brand new for pretty cheap on ebay. And by the way the supra pump is easier to install than the 300zx pump. The 300zx has this hat looking thing that does not let it rotate a full 360 degrees. The supra pump can be rotated all the way around allowing you point the filtered pick up in the right location. The supra pump also pulls more amperage so you'll have to change the fuse out for a higher amp one.

i have the supra pump. its quiet and works well. Denso p/n is 195130-1020. you don't need any mounting hardware, just get the pump itself. use the supra fuel pump sock, or if not, cram the KA filter sock on there.. it fits if you try hard enough. then use some zip ties or hose clamps to clamp the filter to the stock 240 bracket. fits well too.

i got a fuel pump hardwire kit with a separate fuse going off the battery in the trunk, but thats optional.

Don't want supra pump!

*FIT*

I've been considering the supra TT pump for some time now, but wanted to see if anybody else had done it before and what kind of issues they ran into during installation. Sounds like it will be an easy swap...at least much easier than changing the pump out on my previous '91 acura integra where the gas tank has to be dropped. Who in the hell came up with that design anyways? Damn druggies.

And Sandy sx, I have no idea what you mean. Please clarify with more than one 4 word sentence

yea, its easy.. almost a direct fit. its not too expensive either .. i think around 150 for the denso. walbro is only $100, but i hear satifaction w/ them is 70/30

[OKRB20DET]

she said she doesn't want a supra pumpand then threw a fit...

[BoostFab]

go with an Aeromotive fuel pump....best you can get...even the supra guys ditch their pump for a dual walbro. i'm pretty happy with my walbro.

Thank god! Someone who understands me!

The Bosch 040's seem to be a healthy alternative to the Walbro 255's. Whatever you do, do not get anything less that a Walbro or Bosch. Aeromotive A1100's are also popular for the higher horse power setups and using an intank Walbro 255 or Bosch 040 with a inline Walbro GSL392 or Bosch 044 are also great setups for setups exceeding 500/600 horse power.

2nd vote for MKIV pump... I have one... awesome. Winybros are ok, but the quiet "OEM" quality of the 4th gen supra's pump is awesome (on top of it's really good flow characteristics)

Install is really easy... the only thing I had to do was trim the rubber isolator a bit with a dremel (won't take more than a min).

I have a OEM R32 GTR pump, works great.

[SeVa-S13]

I used a Walbro in my first swap with no problems, and I really like it being a bit louder than stock; useful to make sure it's turning on. I'll probly be stepping it up for the next swap though, undecided as of yet on which pump exactly, but the Bosch is sounding nice.

Oh, and Bronze; a friend of mine in Hawaii (supposedly) had a Tomei pump and it was the loudest damn pump I've ever heard. Windows down, 30mph, stupid fartcan on his SR blarring, I could still pick out the pump's distinctive whine..

[Carl H]

ive found that my rb20 runs best when i fill the tank up on hopes and dreams...

You mean what the average new 20 owner can afford?

[ecr33noob]

i have a supra tt fuel pump...works like a champ

[sil_eightyRPS13]

big ups for the bosch....i run it inline under the hood with my R33 in the tank...lotsa pressure!!!

[krayton]

aeromotive inline fuel pump

nice fatty -10an fittings to and from fuel cell

I dont see why you would go with anything other than a Walbro for an in-tank fuel pump. Think about it. ~$100 gets you 255Liters Per Hour. Thats 255,000cc/hour which is 4250cc/min which equals 416.6 lbs per hour. With a .55 BSFC that would support 757.5 HP!! And it is plug and play installation. I recomend walbro to all my customers and have never had a problem or heard a complaint. But the desicion is always up to you!

[Darius]

That is total misinformation. Sorry man. A standard 255 lph walbro will not supply 255 lph at 25 psi boost with a 1:1 rising rate FPR. Say your base fuel pressure is 43 psi. Add 25 psi of boost and you're at 68 psi of fuel pressure to pump against. Unless this pump has a completely flat pump curve over this range (which it doesn't), it will NOT pump 255 lph. In fact, at the aforementioned 68 psi, it only flows 35 gph=132 lph=2200 cc/min which results in each of 6 cylinders with 367 cc/min. Far from supporting 760 hp.

Here's the pump curve for some reference...http://www.lightningmotorsports.com/walbro.htm

As you can see from the plot, the flow from the std walbro drops off after 60 psi. If you are operating your motor at that point, you will likely need the high pressure 255 lph pump, a better aftermarket pump, or higher voltage supply to the pump.
