Yeah... The big problem also is you still have the small bulk head fitting at the top so no additional volume of fuel can flow. The largest restriction is the fittings and lines, Then power, then the pump itself if you have a DW which fits correctly and still offers surge protection in corners.

Not dogging on you, but I've talked to a few reputable tuners and they all have conflicting info on the fitment of the 465. My tuner (who is very well known on the boards here) told me to get the 465, and it makes sense to me more so than the DW65.

I'm looking at the Walbro 465 for a friend among other things, did you ever get this to fit in properly? This seems like an easy upgrade if so. I've done fuel pumps in 08+ STi, just not sure how fitment is here




EDIT: I posted in your thread earlier and didn't see your fuel mods. Nice work, glad to see that it fits! This is another great choice!

So, what is the conclusion here? I've already determined that Clark Turner is extremely unprofessional and immature and likes to talk down to people that don't have a large turbo, but I'm still unsure as to the fitment of the pump in the housing. From what I can tell, Clark Turner was blatantly wrong and belligerent about it.

I do believe pet3r is running this pump, with the bucket attached, and hardwired, but I'm not positive on all this. Even with the restrictive top section I'd have to assume this will flow more than a Walbro 255 or DW300, but I don't know how much more or if there's any way to open it up.

If anyone can confirm fitment of this pump, that would be great. Otherwise I'll just buy one and see what happens.

If the walbro465 is the same size as the walbro400 like i'm running, then YES, it will fit.

It's a bit different. But based on this article I'm starting to think the 405 might be a better option. Good to know it fits.

FYI for all of y'all, yes y'all. LOL!
heres something I copied and pasted from a review I found.



405 vs 465 LPH Pumps...The Real ComparisonSince TI Automotive (owner of Walbro) released the fabulous 405 lph DCSS fuel pump last year, many of us have long awaited the "465 lph" version. The DCSS465 promised higher performance, complete E85 compatibility, same dimensions as the 405, and slightly higher pricing...it sounded almost too good to be true. See for yourself:

E85 COMPATIBILITY
The 405 can expect a 15% shorter life expectancy in E85 compared to the 465. Considering the 465 has an average life expectancy of 10,000 hours in E85, we can expect the 405 to live 8,500 hours in the "corn." If you drive your car an average of 45mph, that is still 382,500 miles. Let's face it, the 405 is absolutely fine in E85.

I have used the 465 for a while now. Its a great pump. There is no point for dual 255 or 300 class pumps any more.

The 400 or the 465 wont fit the later cars with the plastic housing because the pump flares out. The pic above shows how it was hacked in. The bottom of the basket is left off. There is no more surge tank. This wont work for most people that will actualy race the car.

The other drawback here is that you are not using larger lines or fittings which is the real bottle neck when trying to use E85 at high power. The other drawback is the the wiring. These larger pumps pull alot of power. They will smoke the fuel pump controller. You need to run 10awg wire from the battery back to the pump with a simple relay. The latest Cobb Protuner can tune/turn off the Fuel pump controller properly for running a big single pump.

So the choice is yours, You can hack it up like this guy did and leave the entire pump housing off and still use stock fittings and lines, Or you can do it right and put lines and proper wiring. We race are cars and having the housing off like that is not an option. A few third and 4th gear pulls for some logs is one thing. Having fuel while racing is another.

If you dont have a high power setup like this guy, Then you might get away with it. But for cars we build that make high HP, this kind of thing wont work period.

Damn Clark... For coming off as a hard ass know it all you sure can't spell. "We race are cars"... Lol! I haven't had problems with fuel cutout flying thru right hand sweepers at speed... (i'm a warrior out there in the canyons and backroads) In order to get the either one of the pumps to fit, you have to shave off all the tabs off the pump housing with a chisel or dremel to fit. BTW What is this talk about the bottom of the basket being left off? I have mine attached...

You can convert to the old style Fuel pump unit and then hack up a mount for the 465. Or you can get the Full blown fuel pump hanger and use that to install the pump.

C
Wouldn't the full blown hanger be just as bad as using the plastic housing without the bottom? I have a full blown hanger uninstalled now and waiting for Squash Performance to finish up their setup that they say will utilize the bucket. Or as an easier option I would like to do the Walbro 465 which seems to be working for Pet3r.

I have my current DW300 hardwired as well. 12 ga to a relay (30 pin) with fuse between relay and battery. Positive from relay (87 pin) to positive of pump then the negative from the relay (85 pin) to chassis ground. Then the switch (86 pin) is connected back to the car. It has been running fine but will this cause the controller to burn out?

Seems to me people are too inclined to shoot the messenger when he tells them something they don't want to hear. Next time be sure you tell him what opinion you want before asking.

And punchjamesarnol, I guess you've never had a typo in your life. And autocomplete has always worked perfectly for you when typing on a smart phone.

Guys, Clark has been tuning for over a decade, he's got a lot of experience. He gave his opinion, he just didn't bother to take the time to sugar coat it. If your ego gets in the way of listening, maybe you shouldn't ask questions.

And no, I'm not one of his customers. I've never met the guy. But he'll be the one tuning my car when the time comes.

Read through this and have some kind of interesting personal info to add. I installed a DW265 for my current setup on my 08 STi, important bits are a borg warner 7670, aeromotive fpr, and ID1000 injectors. On 93 we started to run out of fuel up top, even after cranking up the fuel pressure a bit, so i ended up going with a Full Blown 340lph pump which solved the issue.

So two things here, why no talk of the full blown, which falls nicely in between the two pumps being discussed on here?

And, anyone else run into a DW265 that didn't seem to be flowing what it should?

Walbro 465 fits. I did it last night with my friend and we were able to get the whole assembly back together. I had to cut a little slot in the cylinder where the pump slides into to make room for the pump pig tails.

This has been my fourth fuel pump install so it wasn't my first time messing with this. My housing was already shaved to fit a walbro 255 and I had a DW300 in that FAILED yesterday hence the Walbro 465 install. The fourth was a friends dw65 pump install.

And yes, we could have skipped the weather pack connector. Hindsight. Either way it is together. And yes we used heat shrink butt end crimp connectors. If the connectors fail ill be sure to post here to warn others.

I am one of those poeple. I am running out of fuel at higher pressures. I love the fitment of the 65c, but I am NOT convinced that this pump outflows even the Walbro 255 under load. I am installing new o-rings this weekend to see if that helps. I have replaced every other f'n thing trying to track down the fueling issue. I am convinced that it is the pump at this point.

My pump is direct wired - 13.6 volts - measured at the fuelpump
I have an aftermarket FPR - set at 45 lbs base pressure
DW 850cc injectors.

I am at 70% injector duty cycle on an 18G at 15lbs boost on 91 octane. Something is not right eh..........

Sorry, didn't realize there was more posts on this

The stock canister was not hacked other than what is required to fit the Walbro 255. The canister was closed (snug fit, but closed just fine), and the pump was hardwired direct to the battery. Was working great, but sold the car.

So, I'm not sure what you're talking about Clark with lots of hacking, or leaving off half of the canister. Mine fit and functioned just fine.

In your picture it shows the missing canister. This is why it does not fit properly. It will work but this is not the right thing to do for a car that will turn left or right. Fuel will slosh away from the pump pick up.

I heard that car blew up recently at a subaru meet and that is why it was sold off. Leaned out? Who knows.

Xluben and I have ours installed with the bottom on as well. It does seem as though the lines or fittings are holding the pressure up. We can't seem to go below 50 psi at idle.

I have -6 AN lines in the engine bay only and Xluben an I are both running a Fuelabs regulator.

Squash Performance is working on a canister setup to solve our issues at this time. Fingers crossed. I think Xluben might be modifying his can to open up the fittings.

Just saw this.

Sounds like you're going through almost exactly what i did. No rhyme or reason i should have been out of fuel with the setup i was running. We swapped out pretty much every part of the fuel system one by one and still ran into the same problem. Finally threw on that full blown 340 and everything was as it should be.

Gonna agree with you on this one, my .02 is that the dw pump might actually flow less than a walboro 255. We should've tried out the walboro too to see if it ran out of fuel as well, but I was beyond frustrated at that point and just wanted the car to run.

So far there are three people who have recently installed this pump into the 08+ plastic housing (me, pet3r, and jockeygolfs). This includes the outer can. It basically fits exactly like a Walbro 255. I'm really not sure why Clark is still confused about this.
