Fuel pump upgrade...

[Neinris]

Can the top in tank canister be cleaned out, say with water, or does it need to be replaced? Or is it fine to be reused and don't bother messing with it?

Not sure what you're referring to, man. Did you pull your pump?

Nope, I didn't pull it out yet. I don't have the torx nut driver to flip my rear seat up yet. I tried a 12 point nut driver, but it was slipping, I didn't want to further do any damage. And aside from the ghost ODB fault codes that I'm having, she's running pretty good right now. Perhaps in spring, after I get back from visiting my family at the end of the month.
Anyway, what I was referring to is the top canister which covers the top of the fuel tank. The one that the hoses and electrical connection hooks up to. I'm not really sure, but I think it's another evap canister? Not sure if those are good forever (for a long time anyway) or needs to be replaced? Or is it part of my issue right now? I'd sometimes see P043E, F, and P fault codes. I apologize I'm rolling into my other issues right now.

Adam, thanks for providing me this link I was able to do more research on my own:
https://partcat.com/delphi?_ga=2.171...291.1615083772

I want to get everyone up to speed and reiterate the base line for the 09- and 09+ Yaris (as previously mention has different fuel pump motors and housings that resides in the basket), here's the most pertinent information according to Delphi's website:
09- Yaris
Avg amp draw: 5
Avg flow rating: 29gph (multiply 3.7854118 for LPH conversion)
Max PSI: 50

09+ Yaris
Avg amp draw: 10
Avg flow rating 26gph
Max PSI: 100

In my research, I want to make correction to the information that was previously provided about the 2008 Corolla fuel pump. There's a product info provided in the site that's confusing. If you select electric fuel pump, it shows an image of a motor with a longer can, which won't be a direct drop in for any of the Yaris. Here's the specs:
Avg amp draw: 5
Avg flow rating: 33gph
Max PSI: 106

But if you select "Fuel Pump and Strainer Set", which is the direct drop in swap, the following specs is given:
Avg amp draw: 6
Avg flow rating: 26gph
Max PSI: 65

So this is debatable as far as considering it as an upgrade if you compare it to the 09- Yaris' stats. I think the 09- Yaris wins this fight, not only is it drawing less amp, but also delivering more gph regardless of the max psi it produces.

In my search for an alternative drop in upgrade for the 09- Yaris, I found that the 08 RAV4 has the same motor design. It has the following specs:
Avg amp draw: 10
Avg flow rating: 30gph
Max PSI: 120

For the 1gph gained, I don't think doubling the amp draw is justifiable, although the max psi will be more than doubled. Comparing it to the 09+ pump on the other hand it wins on all accounts. With all that said, I am still considering it as a possible upgrade for the 09- Yaris.

I've checked the other vehicles with the same motor can design, Avalon, Camry, Solara, frankly the RAV4 beats all of them and the 09- Yaris is actually better.

For the 09+ Yaris, a possible drop in option would also come for the RAV4, but the 2013 generation non-Japan built. It has the following specs:
Avg amp draw: 10
Avg flow rating: 38gph
Max PSI: 123

It beats the 09+ stats in all accounts, the only thing is it's not guaranteed that it will fit, the pictures shows that they are very similar, I'm just now sure as far as the dimensions yet. If anyone is wondering what pictures I use to compare, I used the pictures provided by www.RockAuto.com. If you're curious as well, you can do your own research.

I'm still leaning towards the 2013 RAV4 fuel pump, to justify the more amp draw, but it will require purchasing the 09+ fuel pump housing.
I hope you all stay tuned!

I completely forgot about this thread...

Picture that CTScott posted shows that the 09+ Yaris has a completely different top than the 09-, see comparison below:

09-

09+

Not sure if 09+ have a "returned" system, but that top hose coupling sure looks big. And the 09+ got rid of the top canister.
