Will be using 2x400lph walbro pumps in my surge tank the new e85 set-up.. Can't give any feed back on them yet though the fella who's designing and building the tank reckons they are an awesome bit of kit.. Very well priced as well

I have a feeling I'm only going to need to run one pump though :D

I installed the E85 one in tank in my Gts-t RB25

All is well so far, tune in a few weeks. Easy to install, sucks a lot of power so make sure you have the appropriate wiring

Hey mate, i have one on the way. what did you do to beef up the wiring?

Slighty OT but im wondering if anyone has done anything to bypass the stock plugs intank on the lid?

I usually rewire the intank portion aswell as adding a relay and feed from the battery but it annoys me reusing the stock plugs and crusty old wiring to get throught the lid.

I added 2 posts with 5mm stainless threaded rod and a series washers and nuts to come through the stock plastic lid in a 33gtr. To seal it i used injector orings bellow the bottom washer and applied some pressure when tightening the nuts down. Could be worth trying RS components they might do a proper bulk head fitting to do the same thing.

I hope your upgrading your alternator if you plan on running 2 of these.

Hmmm will need to figure out the current draw for each pump and go from there.. Like I said I'll probs only use 1.. The other one is in there because the tank is a proto type and we wanted to run 2 to see how it goes

By my calculations one on 13.5V is enough to feed 1000cc injectors at 25psi boost (assuming base pressure of 3bar)

Considering that we usually run a touch higher than that voltage on our cars, they should be good for a bit over 600rwhp (on a Dyno Dynamics) on E85

At the following pump pressure on 13.5 volts it draws the following below, so double that if running 2 pumps. Thats a lot of current draw, even 1 pump is a fair amount of current draw.

at 50 psi - 14.88 amp

at 60 psi - 15.64 amp

at 70 psi - 16.45 amp

Righto cheers lads, I've messaged the guy whos putting it all together. I assume he's already figured all this out but it would be good to know how's it's going to peice together.. Will report back once I have the solution/ or when car is up and running

My bad, I'm talking about the big E85 one the F90000267 so it flows even more and also needs more juice to run... Mine should run about 18amps under load.

I have run 25amp wire, a 30amp circuit breaker and relay to mine so I should be ok. The only issue (as someone else has mentioned) is the stock lid of the fuel tank

circuit breakers are to protect the circuit, if youre running '25a' wire, your breaker should be under the rated cable size.

bumping an old topic,

hows everyones walbro 400lph holding up so far with E85?

also came across a newer "450lph" e85 version, any opinions on these?

http://www.ebay.com.au/itm/Walbro-450-LPH-In-Tank-E85-High-Pressure-Fuel-Pump-Install-Kit-F90000267-/150845458543?pt=AU_Car_Parts_Accessories&hash=item231f17086f

im assuming from what ive read here the 400lph one would suffice for around 380rwkw on e85?

Walbro F90000267 (416L/hr E85 rated one) tuned yesterday on my Green Gts-t...

No signs of running out of fuel and the 1200cc injectors were showing 75% duty which shows they can pump at least enough to outflow 900cc injectors (and should do a fair bit more). Fuel pressure was around 70psi on boost

Cheap, nice and quiet, easy to install. Only downside is they suck a lot of power so just make sure your wiring is up for it.

I would recommend these for all in tank installs instead of Bosch 044/040 or Nismo etc

      Yes, I know🙄 but the sequential is not in my budget... don't want to reduce power neither, so looks like I'm stuck in the rabbit hole🤣

      You’ll be very upset when you bust that too not to mention the gearing totally sucks. Don’t do it.

      Is the panel filter one that is oiled? Have you ever cleaned or touched the AFM?

      So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch

      It is the stock air box with the panel filter. Everything else is stock except the exhaust at this point, as I also went back to the cleaned 270cc injectors. I will check the RPM when the IACV is unplugged and report back.
