I've searched and searched and cant find any info on the new Walbro 465 fuel pump and how to fit it to any cars. I have an 08 STi and need to upgrade my pump, but I don't know how to adapt to the car.

Are there kits? Does it drop in pretty much like the 255? What kind of mods are necessary to fit it?

Any info appreciated!

It does not fit in any sense of the word. The 08 STI uses the crappy plastic fuel pump unit. You need the DW65C fuel pump which is more then enough for your little Dom 1.5.

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.

I already have the Walbro 255...the DW265 isn't much of an upgrade. I've heard the 465 drops in, and also heard that it does not. Just not a lot of info out there.

You just heard from Clark Turner, that it won't fit.

THE Clark Turner, you may want to look him up.....

If Mr.Turner says it won't fit, you can take that to the bank, it won't.

Use the suggested DW65C or an Aeromotive 11141, a much better pump than the Wally.

If you already modified the assembly for the 255, putting in the 465 is relatively trivial.

Stealth, did you even read my reply? I'm looking for any info I can find on fitment. One mans response is little. I don't care if it doesn't fit in the stock canister, but more about how it can be adapted to the car.

Wicked, thanks for info.

As I said, The 465 wont fit and it wont fit even if modified for the 255 walbro. The base is much much larger and it has twin props inside. You would have to hack the entire canister up to make it work.

Thank you for being more specific. But, your response conflicts with other reports, including those who have posted in this thread. Just wishing there was more concrete info out there.

Then buy one and install it peter. You need the DW65C pump. That pump is the correct size and fitment for your 08 STI, It also is overkill for your little peanut turbo even on E85

OK, well the current 255 runs me lean at peak boost, around 26psi. Are you saying the DW65c will give me 25% more flow? That's at least what I need for the headroom. Just looking at specs it runs 265lph, vs 255lph on the Walbro, so clearly I'm not getting how an extra 3.4% in flow potential is gonna help me at this point.

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.

Will you stop.. The 465 wont fit Period. If someone told you to get it, They are thinking you are going to modify the system or convert it to the old style hanger and mod that to make it fit. The only pumps that fit that car directly are the stock pump and the DW65C pump. Both are shorter and fit inside the housing.

There is no way in this lifetime that your little turbo is taxing a single pump. Maybe you are out of injector? Maybe your O ring is leaking inside the housing. Thats my guess. the housing is not made for the 255 and you have to cut the housing up to MAKE the 255 FIT. If that was not done properly, OR it was not done at all, Then its probably leaking at high pressure on boost.

I'm sorry that legitimate questions really bother you. You might have a reputation but so do others, and when the majority of them conflict with the information you are posting here it makes me wonder...

IDC is at 85%, running 1000s. Pump is maxed, can't get more out and I'm running lean with the Walbro255. And yes, the canister was modified but thanks for assuming I'm an idiot.

I'm glad you know more about my tune than my tuner, clearly he is wrong or something is wrong with my car because you MUST be right.

What ever. This is pointless to go on. I tried to help. You have had an attitude the entire time. Good luck.

Your question implies you want it to 'drop in' and when told it won't you cop an attitude?

Your little baby WallyPump is inadequate and you where referred to two other, better pumps that DO drop in.

Question answered, problem is now the attitude at the receiving end.

Where is the attitude my friend? He recommended a drop-in pump that flows equally the same as my current pump. I responded accordingly. I got one response and bumped the thread asking if anyone else had experience with installing this pump. Never did I say "IT MUST FIT OMG" like you are implying. And simply saying "it won't fit" doesn't really help. I know it won't "drop-in", but because other tuners have said it can, that is the whole point of this post, trying to decipher what is right and what is wrong. I don't just take some internet persons written statement as gospel, I think, research, do as much as I can until I can't find a solution and then ask for help.

Then you jump in worshiping Clark, and I assumed (sorry mate) you did not read my reply because I clearly don't need the DW65c that you both are so heavily pimping, when it will do me no good. I know the DW65 fits, but that has no bearing on the solution I was asking for.

I don't know why both of you feel like you need to diminish my stature, but clearly it makes you both feel better. Sure, my turbo is "small". Big whoop. My fuel pump is also small, thats EXACTLY why I posted this thread, I already knew that. But that makes you feel better pointing it out how small my "gear" is. Oh well, such is the internet.

Sorry if im late to the party but it sounds like you should use the Full Blown dual pump hanger. This will give you the extra volume you are looking for.

True Joe, But for his dom 1.5 that would not be needed.

Thanks for the link, I had no idea thats what clark was mentioning when he said "full blown" hanger.

Thanks for the bump Clark, but, I'm at the very edge of fuel on my tune. I could add more timing and boost, but then that would be bad. I need more fuel. I'd rather not have to hack together my own canister, so if a dual 255 setup would be the easiest install path then this might be a good option.

24psi @ 5965rpm, 24* timing and 97% IDC = I'm running out of fuel with power on the table still, at the point where I need new injectors too

Just thought I'd give an update as I have solved my fueling issue. During some upgrades I pulled the pump out and had a Walbro 465 on hand. Since I already had a Walbro255 in there previously, the tabs in the housing were ground down already. The W465 dropped right in, ZERO extra modification.

I purchased it along with an install kit and it had a new filter. The filter was bigger than OEM so that was the only thing that made it harder to fit into the stock canister. The housing slid together just fine.

I soldered the electrical lines + shrink wrap and was a cinch.

So, if your 255 pump fits, so does the 465.

WOWOWOW. I need to do this!!! I'd probably just hardwire it all during the install though.

You going to leave the bottom of the fuel pump canister off?

BTW, Dont hook that to the stock fuel pump controller, It will burn it out shortly.
