Walbro F90000267 E85 Pumps , Not Too Big For Road ?

Hi all , if your sick of fuel pumps threads go elsewhere .

As many know I've been searching and asking about suitable E85 EFI fuel pumps for road use and from what I've read/heard pumps like Bosch 044s Nismos may not live long lives because ethanol doesn't lubricate like petrol does . I like the Nismo R33 GTR pump but it's a lot of money to throw at a pump that may wear out in a few years .

The E85 pump that keeps popping up is this Walbro F90000267 which is a turbine pump and it's said to be very quiet .

At 450 lpm it's not short of flow though too much can be a problem fuel heat wise .

The other thing is that these pumps have the ability to drag high current at higher fuel pressures and this has caused problems at the tank lid terminals (R33) . Insight sells a gadget to get wiring into fuel tanks and I'll ask Scott about that one .

Is anyone here using this fuel pump and do you get fuel heating issues ?

I have personally installed 5 or 6 of them, and sold many more without any complaints. They are almost silent if installed correctly, more so than the old 255's, and are specifically designed for e85 use. It's a no brainer imo, as I am sure many people have told you already.

Yes the fuel gets hot after a few hours on the dyno, but how is that the fault of the pump? It's the rail that is hot, why don't you look at super cooling the rail with liquid nitrogen or something. :P

Do you need the massive flow? Haven't used these specifically, but the likes of DW300 fuel pumps are quite fine with ethanol - quiet and all that good stuff and probably more suited to the amount of flow you need.

Walbro in-tank is $165, on a 45% off special - so normally easily over NZD$200: http://www.nzperformance.co.nz/fuel-system/walbro-fuel-pumps.html

But even then only $55 (~30%) more than:

Both are NZD$300 normal price.

Great price on the 300 there, much cheaper than my supplier, but then they never did like buying them in for me.

I sell the e85 Walbro's for $200, why would you bother with anything else at that price, especially if you plan to run ethanol at any percentage.

Very minor mods needed.

As in.. soldering.

Having had the fun of putting an 040, 044, GTR, DW301, and now the Walbro 460LPH pump, I can say they're all of equal difficulty to fit, and the DW300 and Walbro 460LPH pump are both equally quiet (silent compared the rest)

I needed to modify my stock cradle to fit the pump in tank, as the 460LPH pump is too big to fit in the same position. But again, very minor stuff, took 5 minutes.

Greg I'd like to hear your opinions of the DW301 and the Walbro 460 Ethanol pumps .

This is a thread from NASIOC that has the performance data for the DW301 .

http://forums.nasioc.com/forums/showthread.php?t=2102897

It sounds like a good thing and DW seems to have gone all out SAE testing them on E100 .

I like the 13.5v table figures and if not pushing more than about 60 psi the current draw should be easy on an elec system with adequate wiring .

There is a fitting kit to suit their 240SX and this may make it virtually an easy install on a GTS25Ts bracket .

I had a look at the standard wiring in my R33 since the back seat was out and the wire size is not brilliant , it's really small at the FPCM plug .

Thanks for the tip Lith , cheers A .

The solution? Your questioning it. Looking for ways around it. Just search, see what the eons have done before you. E85 is so well covered these days its not funny. Drop in a big in tank, silent, easy to install, no fuss pump. Oh wait, you want to make a diamond from dogshit. Go right ahead.

      Who has a Infiniti Q60, Q50 (V37)?

      By Duncan · Posted

      The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.

      Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?

      R34 25GT Engine Light 21

      By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol

      No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.
